138-618: The Neo Geo Pocket Color ( NGPC ) is a 16-bit handheld game console developed and manufactured by SNK , released on March 19, 1999 in Japan with international markets following in August that year. It is the successor to the Neo Geo Pocket , which was released in 1998 only in Japan and Hong Kong; the Color features a color display instead of a monochrome one, and is fully backward compatible . Although
276-478: A bullet train , saw a bored businessman playing with an LCD calculator by pressing the buttons. Yokoi then thought of an idea for a watch that doubled as a miniature game machine for killing time. Starting in 1980, Nintendo began to release a series of electronic games designed by Yokoi called the Game & Watch games. Taking advantage of the technology used in the credit-card-sized calculators that had appeared on
414-623: A pre-order incentive for Samurai Shodown (2019). These re-releases were later compiled into Neo Geo Pocket Color Selection Vol. 1 (2021) and Vol. 2 (2022), which were also released for Windows . SNK sold over 25,000 Neo Geo Pocket Color systems in Japan and over 100,000 in Europe by the end of 1999. By May of 2000, the Neo Geo Pocket Color retained a 2% market share in the North American handheld market; although minuscule compared to
552-636: A 1024 GB flash chip, with eight stacked 96-layer V-NAND chips and with QLC technology. Flash memory stores information in an array of memory cells made from floating-gate transistors . In single-level cell (SLC) devices, each cell stores only one bit of information. Multi-level cell (MLC) devices, including triple-level cell (TLC) devices, can store more than one bit per cell. The floating gate may be conductive (typically polysilicon in most kinds of flash memory) or non-conductive (as in SONOS flash memory). In flash memory, each memory cell resembles
690-489: A 16 GB flash memory chip that was manufactured with 24 stacked NAND flash chips using a wafer bonding process. Toshiba also used an eight-layer 3D IC for their 32 GB THGBM flash chip in 2008. In 2010, Toshiba used a 16-layer 3D IC for their 128 GB THGBM2 flash chip, which was manufactured with 16 stacked 8 GB chips. In the 2010s, 3D ICs came into widespread commercial use for NAND flash memory in mobile devices . In 2016, Micron and Intel introduced
828-433: A 64 MB NOR flash memory chip. In 2009, Toshiba and SanDisk introduced NAND flash chips with QLC technology storing 4 bits per cell and holding a capacity of 64 Gbit. Samsung Electronics introduced triple-level cell (TLC) technology storing 3-bits per cell, and began mass-producing NAND chips with TLC technology in 2010. Charge trap flash (CTF) technology replaces the polysilicon floating gate, which
966-499: A USB cable from a PC. The GP32 was redesigned in 2003. A front-lit screen was added and the new version was called GP32 FLU (Front Light Unit). In summer 2004, another redesign, the GP32 BLU, was made, and added a backlit screen. This version of the handheld was planned for release outside South Korea; in Europe, and it was released for example in Spain (VirginPlay was the distributor). While not
1104-594: A backlit screen was released in some regions around the same time. Along with the GameCube , the GBA also introduced the concept of "connectivity": using a handheld system as a console controller. A handful of games use this feature, most notably Animal Crossing , Pac-Man Vs. , Final Fantasy Crystal Chronicles , The Legend of Zelda: Four Swords Adventures , The Legend of Zelda: The Wind Waker , Metroid Prime , and Sonic Adventure 2: Battle . As of December 31, 2007,
1242-742: A cable to connect the NGPC and the Dreamcast , as part of a partnership between SNK and Sega . Games that featured this option include King of Fighters R-2 (links with King of Fighters '99 Dream Match and King of Fighters Evolution ); SNK vs. Capcom: Match of the Millennium (links with Capcom vs. SNK ); SNK vs. Capcom: Card Fighters Clash (links with King of Fighters Evolution ); SNK vs. Capcom: Card Fighters 2 Clash Expand Edition (links with Capcom vs SNK ) and Cool Cool Jam (links with Cool Cool Toon ). A total of 73 games were released for
1380-548: A certain number of faults (NOR flash, as is used for a BIOS ROM, is expected to be fault-free). Manufacturers try to maximize the amount of usable storage by shrinking the size of the transistors or cells, however the industry can avoid this and achieve higher storage densities per die by using 3D NAND, which stacks cells on top of each other. NAND flash cells are read by analysing their response to various voltages. NAND flash uses tunnel injection for writing and tunnel release for erasing. NAND flash memory forms
1518-517: A charge-trapping mechanism for NOR flash memory cells. CTF was later commercialized by AMD and Fujitsu in 2002. 3D V-NAND (vertical NAND) technology stacks NAND flash memory cells vertically within a chip using 3D charge trap flash (CTP) technology. 3D V-NAND technology was first announced by Toshiba in 2007, and the first device, with 24 layers, was first commercialized by Samsung Electronics in 2013. 3D integrated circuit (3D IC) technology stacks integrated circuit (IC) chips vertically into

#17328527044221656-586: A commercial success on a level with mainstream handhelds (only 30,000 units were sold), it ended up being used mainly as a platform for user-made applications and emulators of other systems, being popular with developers and more technically adept users. Nokia released the N-Gage in 2003. It was designed as a combination MP3 player, cellphone, PDA, radio, and gaming device. The system received much criticism alleging defects in its physical design and layout, including its vertically oriented screen and requirement of removing
1794-411: A conversion of Pac-Man , which came with a plastic cross ring that restricted the system's clicky stick to four directions; this version is often seen as one of the best home ports of the game to be released. Compile , Data East and ADK also produced ports of Puyo Pop , Magical Drop and Crush Roller respectively. Success published Cotton: Fantastic Night Dreams , a successful port of
1932-489: A cost-cutting move rather than hard plastic cases that Japanese and European releases were shipped in may have also hurt US sales. The WonderSwan Color is a handheld game console designed by Bandai . It was released on December 9, 2000, in Japan, Although the WonderSwan Color was slightly larger and heavier (7 mm and 2 g) compared to the original WonderSwan, the color version featured 512 KB of RAM and
2070-467: A dearth of compelling games, and Nintendo's aggressive marketing campaign, and despite a redesign in 1991, the Lynx became a commercial failure . Despite this, companies like Telegames helped to keep the system alive long past its commercial relevance, and when new owner Hasbro released the rights to develop for the public domain, independent developers like Songbird have managed to release new commercial games for
2208-463: A different architecture, relying on a serial access approach. This makes NAND suitable for high-density data storage but less efficient for random access tasks. NAND flash is often employed in scenarios where cost-effective, high-capacity storage is crucial, such as in USB drives, memory cards, and solid-state drives ( SSDs ). The primary differentiator lies in their use cases and internal structures. NOR flash
2346-501: A fast read access time but it is not as fast as static RAM or ROM. In portable devices, it is preferred to use flash memory because of its mechanical shock resistance since mechanical drives are more prone to mechanical damage. Because erase cycles are slow, the large block sizes used in flash memory erasing give it a significant speed advantage over non-flash EEPROM when writing large amounts of data. As of 2019, flash memory costs greatly less than byte-programmable EEPROM and had become
2484-630: A flight simulator, included a "head-to-head" dogfight mode that can only be accessed via TurboLink. However, very few TG-16 games offered co-op play modes especially designed with the TurboExpress in mind. The Bitcorp Gamate is one of the first handheld game systems created in response to the Nintendo Game Boy. It was released in Asia in 1990 and distributed worldwide by 1991. Like the Sega Game Gear, it
2622-480: A good sales start in both the U.S. and Japan with 14 launch titles (a record at the time), subsequent low retail support in the U.S., lack of communication with third-party developers by SNK's American management, the popularity of Nintendo's Pokémon franchise and anticipation of the 32-bit Game Boy Advance , and strong competition from Bandai 's WonderSwan in Japan, led to a sales decline in both regions. Meanwhile, SNK had been in financial trouble for at least
2760-456: A laptop computer), as well as a frontlit color display and rechargeable battery. Despite the smaller form factor, the screen remained the same size as that of the original. In 2005, the Game Boy Micro was released. This revision sacrifices screen size and backwards compatibility with previous Game Boys for a dramatic reduction in total size and a brighter backlit screen. A new SP model with
2898-470: A larger color LCD screen. In addition, the WonderSwan Color is compatible with the original WonderSwan library of games. Prior to WonderSwan's release, Nintendo had virtually a monopoly in the Japanese video game handheld market. After the release of the WonderSwan Color, Bandai took approximately 8% of the market share in Japan partly due to its low price of 6800 yen (approximately US$ 65). Another reason for

#17328527044223036-406: A line of calculator-sized sports games that became the world's first handheld electronic games. The project began when Michael Katz, Mattel's new product category marketing director, told the engineers in the electronics group to design a game the size of a calculator, using LED (light-emitting diode) technology." The result was the 1976 release of Auto Race . Followed by Football later in 1977,
3174-534: A lot of power, they were not battery-friendly like the non-backlit original Game Boy whose monochrome graphics allowed longer battery life. By this point, rechargeable battery technology had not yet matured and so the more advanced game consoles of the time such as the Sega Game Gear and Atari Lynx did not have nearly as much success as the Game Boy. Even though third-party rechargeable batteries were available for
3312-444: A major feature of the Game Boy line, since it allowed each new launch to begin with a significantly larger library than any of its competitors. As of March 31, 2005, the Game Boy and Game Boy Color combined to sell 118.69 million units worldwide. The console is capable of displaying up to 56 different colors simultaneously on screen from its palette of 32,768, and can add basic four-color shading to games that had been developed for
3450-674: A major leap in innovation, particularly in the second half with the release of the DS and PSP . In 2001, Nintendo released the Game Boy Advance (GBA or AGB), which added two shoulder buttons, a larger screen, and more computing power than the Game Boy Color. The design was revised two years later when the Game Boy Advance SP (GBA SP), a more compact version, was released. The SP features a " clamshell " design (folding open and closed, like
3588-585: A million units were sold in the US. As of March 31, 2005, the Game Boy and Game Boy Color combined to sell over 118 million units worldwide. In 1987, Epyx created the Handy Game; a device that would become the Atari Lynx in 1989. It is the first color handheld console ever made, as well as the first with a backlit screen. It also features networking support with up to 17 other players, and advanced hardware that allows
3726-425: A more typical 10,000 or 100,000 erase cycles, up to 1,000,000 erase cycles. NOR-based flash was the basis of early flash-based removable media; CompactFlash was originally based on it, though later cards moved to less expensive NAND flash. NAND flash has reduced erase and write times, and requires less chip area per cell, thus allowing greater storage density and lower cost per bit than NOR flash. However,
3864-484: A much higher resolution, and can display 64 sprites at once, 16 per scanline, in 512 colors. Although the hardware can only handle 481 simultaneous colors. It has 8 kilobytes of RAM . The Turbo runs the HuC6820 CPU at 1.79 or 7.16 MHz . The optional "TurboVision" TV tuner includes RCA audio/video input, allowing users to use TurboExpress as a video monitor. The "TurboLink" allowed two-player play. Falcon ,
4002-518: A planar charge trap cell into a cylindrical form. As of 2020, 3D NAND flash memories by Micron and Intel instead use floating gates, however, Micron 128 layer and above 3D NAND memories use a conventional charge trap structure, due to the dissolution of the partnership between Micron and Intel. Charge trap 3D NAND flash is thinner than floating gate 3D NAND. In floating gate 3D NAND, the memory cells are completely separated from one another, whereas in charge trap 3D NAND, vertical groups of memory cells share
4140-421: A separate die inside the package. The origins of flash memory can be traced back to the development of the floating-gate MOSFET (FGMOS) , also known as the floating-gate transistor. The original MOSFET was invented at Bell Labs between 1955 and 1960, after Frosch and Derick discovered surface passivation and used their discovery to create the first planar transistors. Dawon Kahng went on to develop
4278-485: A single 3D IC chip package. Toshiba introduced 3D IC technology to NAND flash memory in April 2007, when they debuted a 16 GB eMMC compliant (product number THGAM0G7D8DBAI6, often abbreviated THGAM on consumer websites) embedded NAND flash memory chip, which was manufactured with eight stacked 2 GB NAND flash chips. In September 2007, Hynix Semiconductor (now SK Hynix ) introduced 24-layer 3D IC technology, with

4416-424: A single memory product. A single-level NOR flash cell in its default state is logically equivalent to a binary "1" value, because current will flow through the channel under application of an appropriate voltage to the control gate, so that the bitline voltage is pulled down. A NOR flash cell can be programmed, or set to a binary "0" value, by the following procedure: To erase a NOR flash cell (resetting it to
4554-409: A single supply voltage and produce the high voltages that are required using on-chip charge pumps . Over half the energy used by a 1.8 V-NAND flash chip is lost in the charge pump itself. Since boost converters are inherently more efficient than charge pumps, researchers developing low-power SSDs have proposed returning to the dual Vcc/Vpp supply voltages used on all early flash chips, driving
4692-485: A standard metal–oxide–semiconductor field-effect transistor (MOSFET) except that the transistor has two gates instead of one. The cells can be seen as an electrical switch in which current flows between two terminals (source and drain) and is controlled by a floating gate (FG) and a control gate (CG). The CG is similar to the gate in other MOS transistors, but below this, there is the FG insulated all around by an oxide layer. The FG
4830-472: A technology known as CMOS Under the Array/CMOS Under Array (CUA), Core over Periphery (COP), Periphery Under Cell (PUA), or Xtacking, in which the control circuitry for the flash memory is placed under or above the flash memory cell array. This has allowed for an increase in the number of planes or sections a flash memory chip has, increasing from 2 planes to 4, without increasing the area dedicated to
4968-401: A television screen. Handheld electronic games, in turn, find their origins in the synthesis of previous handheld and tabletop electro-mechanical devices such as Waco 's Electronic Tic-Tac-Toe (1972) Cragstan's Periscope-Firing Range (1951), and the emerging optoelectronic -display-driven calculator market of the early 1970s. This synthesis happened in 1976, when "Mattel began work on
5106-838: A time. NAND flash also uses floating-gate transistors , but they are connected in a way that resembles a NAND gate : several transistors are connected in series, and the bit line is pulled low only if all the word lines are pulled high (above the transistors' V T ). These groups are then connected via some additional transistors to a NOR-style bit line array in the same way that single transistors are linked in NOR ;flash. Compared to NOR flash, replacing single transistors with serial-linked groups adds an extra level of addressing. Whereas NOR flash might address memory by page then word, NAND flash might address it by page, word and bit. Bit-level addressing suits bit-serial applications (such as hard disk emulation), which access only one bit at
5244-453: A time. Execute-in-place applications, on the other hand, require every bit in a word to be accessed simultaneously. This requires word-level addressing. In any case, both bit and word addressing modes are possible with either NOR or NAND flash. To read data, first the desired group is selected (in the same way that a single transistor is selected from a NOR array). Next, most of the word lines are pulled up above V T2 , while one of them
5382-527: A touch screen and stylus. However, Tiger hoped it would also challenge Nintendo's Game Boy and gain a following among younger gamers too. Unlike other handheld game consoles, the first game.com consoles included two slots for game cartridges, which would not happen again until the Tapwave Zodiac, the DS and DS Lite, and could be connected to a 14.4 kbit/s modem. Later models had only a single cartridge slot. The Game Boy Color (also referred to as GBC or CGB)
5520-506: A type of flash memory with a charge trap method. In 1998, Boaz Eitan of Saifun Semiconductors (later acquired by Spansion ) patented a flash memory technology named NROM that took advantage of a charge trapping layer to replace the conventional floating gate used in conventional flash memory designs. In 2000, an Advanced Micro Devices (AMD) research team led by Richard M. Fastow, Egyptian engineer Khaled Z. Ahmed and Jordanian engineer Sameer Haddad (who later joined Spansion) demonstrated
5658-447: A variation, the floating-gate MOSFET, with Taiwanese-American engineer Simon Min Sze at Bell Labs in 1967. They proposed that it could be used as floating-gate memory cells for storing a form of programmable read-only memory ( PROM ) that is both non-volatile and re-programmable. Early types of floating-gate memory included EPROM (erasable PROM) and EEPROM (electrically erasable PROM) in

However, Aruze did not support SNK's video game business enough, leading to SNK's original founder and several other employees leaving to form a new company, BrezzaSoft. Eventually on June 13, 2000, Aruze decided to quit the North American and European markets, marking the end of SNK's worldwide operations and
6072-570: Is Nintendo's successor to the Game Boy and was released on October 21, 1998, in Japan and in November of the same year in the United States. It features a color screen, and is slightly bigger than the Game Boy Pocket . The processor is twice as fast as a Game Boy's and has twice as much memory. It also had an infrared communications port for wireless linking which did not appear in later versions of
6210-401: Is a redesigned version of the original Game Boy having the same features. It was released in 1996. Notably, this variation is smaller and lighter. It comes in seven different colors; red, yellow, green, black, clear, silver, blue, and pink. It has space for two AAA batteries , which provide approximately 10 hours of game play. The screen was changed to a true black-and-white display, rather than
6348-515: Is also often used to store configuration data in digital products, a task previously made possible by EEPROM or battery-powered static RAM . A key disadvantage of flash memory is that it can endure only a relatively small number of write cycles in a specific block. NOR flash is known for its direct random access capabilities, making it apt for executing code directly. Its architecture allows for individual byte access, facilitating faster read speeds compared to NAND flash. NAND flash memory operates with
6486-528: Is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash , are named for the NOR and NAND logic gates . Both use the same cell design, consisting of floating-gate MOSFETs . They differ at the circuit level depending on whether the state of the bit line or word lines is pulled high or low: in NAND flash,
6624-444: Is an electrically insulating tunnel oxide layer between the floating gate and the silicon, so the gate "floats" above the silicon. The oxide keeps the electrons confined to the floating gate. Degradation or wear (and the limited endurance of floating gate Flash memory) occurs due to the extremely high electric field (10 million volts per centimeter) experienced by the oxide. Such high voltage densities can break atomic bonds over time in
6762-518: Is interposed between the CG and the MOSFET channel. Because the FG is electrically isolated by its insulating layer, electrons placed on it are trapped. When the FG is charged with electrons, this charge screens the electric field from the CG, thus, increasing the threshold voltage (V T ) of the cell. This means that the V T of the cell can be changed between the uncharged FG threshold voltage (V T1 ) and
6900-487: Is often considered one of the greatest games produced for the system. Taito contributed a port of their successful arcade game Densha de Go! 2 and Puzzle Bobble Mini , also known as Bust-A-Move Pocket . Capcom worked in conjunction with SNK on several crossover games featuring their characters, including SNK vs. Capcom: Match of the Millennium and the SNK vs. Capcom: Card Fighters Clash series of games. Namco published
7038-484: Is optimal for applications requiring quick access to individual bytes, like in embedded systems for program execution. NAND flash, on the other hand, shines in scenarios demanding cost-effective, high-capacity storage with sequential data access. Flash memory is used in computers , PDAs , digital audio players , digital cameras , mobile phones , synthesizers , video games , scientific instrumentation , industrial robotics , and medical electronics . Flash memory has

#17328527044227176-625: Is programmed in blocks while EEPROM is programmed in bytes. According to Toshiba, the name "flash" was suggested by Masuoka's colleague, Shōji Ariizumi, because the erasure process of the memory contents reminded him of the flash of a camera . Masuoka and colleagues presented the invention of NOR flash in 1984, and then NAND flash at the IEEE 1987 International Electron Devices Meeting (IEDM) held in San Francisco. Toshiba commercially launched NAND flash memory in 1987. Intel Corporation introduced
7314-422: Is pulled up to V I . The series group will conduct (and pull the bit line low) if the selected bit has not been programmed. Despite the additional transistors, the reduction in ground wires and bit lines allows a denser layout and greater storage capacity per chip. (The ground wires and bit lines are actually much wider than the lines in the diagrams.) In addition, NAND flash is typically permitted to contain
7452-484: Is sandwiched between a blocking gate oxide above and a tunneling oxide below it, with an electrically insulating silicon nitride layer; the silicon nitride layer traps electrons. In theory, CTF is less prone to electron leakage, providing improved data retention. Because CTF replaces the polysilicon with an electrically insulating nitride, it allows for smaller cells and higher endurance (lower degradation or wear). However, electrons can become trapped and accumulate in

XGP Handheld game console A handheld game console , or simply handheld console , is a small, portable self-contained video game console with a built-in screen, game controls and speakers. Handheld game consoles are smaller than home video game consoles and contain the console, screen, speakers, and controls in one unit, allowing players to carry them and play them at any time or place. In 1976, Mattel introduced
7728-582: Is the Milton Bradley Microvision in 1979. Nintendo is credited with popularizing the handheld console concept with the release of the Game Boy in 1989 and continues to dominate the handheld console market. The first internet -enabled handheld console and the first with a touchscreen was the Game.com released by Tiger Electronics in 1997. The Nintendo DS , released in 2004, introduced touchscreen controls and wireless online gaming to
7866-513: Is thus highly suitable for use in mass-storage devices, such as memory cards and solid-state drives (SSD). For example, SSDs store data using multiple NAND flash memory chips. The first NAND-based removable memory card format was SmartMedia , released in 1995. Many others followed, including MultiMediaCard , Secure Digital , Memory Stick , and xD-Picture Card . A new generation of memory card formats, including RS-MMC , miniSD and microSD , feature extremely small form factors. For example,
8004-545: The GP2X , use standard alkaline batteries . Because the mAh rating of alkaline batteries has increased since the 1990s, the power needed for handhelds like the GP2X may be supplied by relatively few batteries. Nintendo released the Game Boy on April 21, 1989 (September 1990 for the UK). The design team headed by Gunpei Yokoi had also been responsible for the Game & Watch system, as well as
8142-716: The Master System , which gave Sega the ability to quickly create Game Gear games from its large library of games for the Master System. While never reaching the level of success enjoyed by Nintendo, the Game Gear proved to be a fairly durable competitor, lasting longer than any other Game Boy rivals. While the Game Gear is most frequently seen in black or navy blue, it was also released in a variety of additional colors: red, light blue, yellow, clear, and violet. All of these variations were released in small quantities and frequently only in

This is known as Negative gate source source erase. Newer NOR memories can erase using negative gate channel erase, which biases the wordline on a NOR memory cell block and the P-well of the memory cell block to allow FN tunneling to be carried out, erasing
8694-472: The "pea soup" monochromatic display of the original Game Boy. Although, like its predecessor, the Game Boy Pocket has no backlight to allow play in a darkened area, it did notably improve visibility and pixel response-time (mostly eliminating ghosting ). The first model of the Game Boy Pocket did not have an LED to show battery levels, but the feature was added due to public demand. The Game Boy Pocket

These electronic devices are capable of playing only a single game, they fit in the palm of the hand or on a tabletop, and they may make use of a variety of video displays such as LED , VFD , or LCD . In 1978, handheld electronic games were described by Popular Electronics magazine as "nonvideo electronic games" and "non-TV games" as distinct from devices that required use of
8970-712: The 1970s. However, early floating-gate memory required engineers to build a memory cell for each bit of data, which proved to be cumbersome, slow, and expensive, restricting floating-gate memory to niche applications in the 1970s, such as military equipment and the earliest experimental mobile phones . Modern EEPROM based on Fowler-Nordheim tunnelling to erase data was invented by Bernward and patented by Siemens in 1974. And further developed between 1976 and 1978 by Eliyahou Harari at Hughes Aircraft Company and George Perlegos and others at Intel. This led to Masuoka's invention of flash memory at Toshiba in 1980. The improvement between EEPROM and flash being that flash

Following Sega's success with the Game Gear, they began development on a successor during the early 1990s, which was intended to feature a touchscreen interface, many years before the Nintendo DS . However, such a technology was very expensive at the time, and the handheld itself was estimated to have cost around $ 289 were it to be released. Sega eventually chose to shelve

The original GP32 was released in 2001 by the South Korean company Game Park a few months after the launch of the Game Boy Advance. It featured a 32-bit CPU, 133 MHz processor, MP3 and Divx player, and e-book reader. SmartMedia cards were used for storage, and could hold up to 128mb of anything downloaded through
9798-412: The Game Boy needed a killer app —at least one game that would define the console, and persuade customers to buy it. In June 1988, Minoru Arakawa , then-CEO of Nintendo of America saw a demonstration of the game Tetris at a trade show. Nintendo purchased the rights for the game, and packaged it with the Game Boy system as a launch title . It was almost an immediate hit. By the end of the year more than
9936-424: The Game Boy, such as the Game Boy Advance. The Game Boy Color was a response to pressure from game developers for a new system, as they felt that the Game Boy, even in its latest incarnation, the Game Boy Pocket, was insufficient. The resulting product was backward compatible, a first for a handheld console system, and leveraged the large library of games and great installed base of the predecessor system. This became
10074-537: The I/O interface of NAND flash does not provide a random-access external address bus. Rather, data must be read on a block-wise basis, with typical block sizes of hundreds to thousands of bits. This makes NAND flash unsuitable as a drop-in replacement for program ROM, since most microprocessors and microcontrollers require byte-level random access. In this regard, NAND flash is similar to other secondary data storage devices , such as hard disks and optical media , and
10212-517: The LCD-based Microvision , designed by Smith Engineering and distributed by Milton-Bradley, became the first handheld game console and the first to use interchangeable game cartridges. The Microvision game Cosmic Hunter (1981) also introduced the concept of a directional pad on handheld gaming devices, and is operated by using the thumb to manipulate the on-screen character in any of four directions. In 1979, Gunpei Yokoi , traveling on
10350-445: The NGPC had a 2% market share in the U.S. handheld console market; although tiny compared to the Game Boy and Game Boy Color , it was enough to turn a profit for SNK USA. On 21 October 1999, a redesigned, slimmer version called New Neo Geo Pocket Color was released in Japan, selling at ¥6800. It is 13% smaller than the original Neo Geo Pocket Color, with dimensions 125 x 73 x 27 mm, and also features improved sound output. After
10488-516: The NGPC sold a successful 25,000 units. Prior to SNK's acquisition by Aruze, the Neo Geo Pocket Color was being advertised on U.S. television and units were being sold nationwide at Wal-Mart , Best Buy , Toys "R" Us , and other major retail chains. For the Christmas Holiday season in 1999, SNK spent $ 4 million on television advertisements that aired on channels including MTV , Comedy Central , Cartoon Network and Nickelodeon . By May 2000,
10626-439: The Neo Geo Pocket Color had an exclusive launch on the website eToys in 1999. eToys also sold the initial launch titles in the plastic snap lock cases. The system debuted in the United States with six launch titles (twenty promised by end of year) and retail price of $ 69.95. Six different unit colors were available: Camouflage Blue, Carbon Black, Crystal White, Platinum Blue, Platinum Silver, and Stone Blue. In its first two months,
10764-467: The Neo Geo Pocket Color was dropped from both the US and European markets, purportedly due to commercial failure. The system seemed well on its way to being a success in the U.S. It was more successful than any Game Boy competitor since Sega 's Game Gear , but was hurt by several factors, such as SNK's infamous lack of communication with third-party developers, and anticipation of the Game Boy Advance. The decision to ship U.S. games in cardboard boxes in
10902-526: The Neo Geo Pocket Color. Most of the system's games were produced by SNK themselves, featuring well-received titles from franchises such as Fatal Fury , Metal Slug and The King of Fighters . Several large third-party developers also contributed to the system; the most well known of these is Sega 's Sonic the Hedgehog Pocket Adventure , a title heavily based on Sonic the Hedgehog 2 that
11040-485: The Neo Geo Pocket, it has a color screen in the middle. Similar to the Game Boy and its successors, the Game Boy Color and Game Boy Advance , the Neo Geo Pocket Color does not have a back-lit screen, and games can only be played in a well-lit area. Like the Game.com before it, the Neo Geo Pocket Color uses a CR2032 battery to retain backup memory and keep the clock active, as well as the usual AA batteries to power
11178-527: The Nintendo's Game Boy Color , it was enough to turn a profit for SNK America. Retrospective feedback for the Neo Geo Pocket Color has been positive. USGamer writer Jeremy Parish considers it an important and influential handheld for being a "technological bridge" between the 8-bit portable era and the Game Boy Advance , and for its "clicky stick" having been used for modern video game consoles. He praised
11316-518: The WonderSwan's success in Japan was the fact that Bandai managed to get a deal with Square to port over the original Famicom Final Fantasy games with improved graphics and controls. However, with the popularity of the Game Boy Advance and the reconciliation between Square and Nintendo, the WonderSwan Color and its successor, the SwanCrystal quickly lost its competitive advantage . The 2000s saw
11454-409: The WonderSwan, the Neo Geo Pocket Color may not have succeeded in its goal of wrestling market share away from Nintendo, but that doesn't automatically mean it was a failure. Many fans will argue that the quality of the software available was far in advance of that on the Game Boy Color, and the fantastic controls, amazing battery life, cool PDA features and excellent screen combine to make a system which
11592-460: The arcade game of the same name. Similar to the Neo Geo AES console, Neo Geo Pocket Color games were packaged in large clamshell-like black cases, fitted with bright, colorful cover art on them. As a way to reduce costs, in North America the games were instead shipped in cardboard boxes, a move that has been negatively received due to their general poor quality. Japanese games were later released in
11730-407: The article with: "Neo Geo Pocket Color's life may have been painfully brief, but it was nevertheless memorable for those who experienced it. Perhaps all the more so for the system's brevity, in fact." Ryan Lamble of Den of Geek felt that the Neo Geo Pocket Color was the best rival to Nintendo's Game Boy Color for its "brilliant" game library, design and overall quality. Lamble expressed somber towards
11868-464: The back-stock of systems and games to be flashed and re-sold in Asia where the system would continue to be sold and supported. Some of the back-stock of American NGPC hardware and software began to resurface on the American and Asian markets in 2003. These units frequently appeared bundled with six games stripped of their cases and manuals. Two games often included, Faselei! and The Last Blade: Beyond
12006-523: The battery to change game cartridges. The most well known of these was " sidetalking ", or the act of placing the phone speaker and receiver on an edge of the device instead of one of the flat sides, causing the user to appear as if they are speaking into a taco . The N-Gage QD was later released to address the design flaws of the original. However, certain features available in the original N-Gage, including MP3 playback, FM radio reception, and USB connectivity were removed. Flash memory Flash memory
12144-446: The battery-hungry alternatives to the Game Boy, these batteries employed a nickel-cadmium process and had to be completely discharged before being recharged to ensure maximum efficiency; lead-acid batteries could be used with automobile circuit limiters (cigarette lighter plug devices); but the batteries had mediocre portability. The later NiMH batteries, which do not share this requirement for maximum efficiency, were not released until
12282-466: The cell block. Older memories used source erase, in which a high voltage was applied to the source and then electrons from the FG were moved to the source. Modern NOR flash memory chips are divided into erase segments (often called blocks or sectors). The erase operation can be performed only on a block-wise basis; all the cells in an erase segment must be erased together. Programming of NOR cells, however, generally can be performed one byte or word at
12420-502: The cell by increasing the MOSFET's threshold voltage. This, in turn, changes the drain-source current that flows through the transistor for a given gate voltage, which is ultimately used to encode a binary value. The Fowler-Nordheim tunneling effect is reversible, so electrons can be added to or removed from the floating gate, processes traditionally known as writing and erasing. Despite the need for relatively high programming and erasing voltages, virtually all flash chips today require only
12558-402: The cells are logically set to 1. Data can only be programmed in one pass to a page in a block that was erased. The programming process is set one or more cells from 1 to 0. Any cells that have been set to 0 by programming can only be reset to 1 by erasing the entire block. This means that before new data can be programmed into a page that already contains data, the current contents of the page plus
12696-584: The control or periphery circuitry. This increases the number of IO operations per flash chip or die, but it also introduces challenges when building capacitors for charge pumps used to write to the flash memory. Some flash dies have as many as 6 planes. As of August 2017, microSD cards with a capacity up to 400 GB (400 billion bytes) are available. The same year, Samsung combined 3D IC chip stacking with its 3D V-NAND and TLC technologies to manufacture its 512 GB KLUFG8R1EM flash memory chip with eight stacked 64-layer V-NAND chips. In 2019, Samsung produced
12834-404: The core of the removable USB storage devices known as USB flash drives , as well as most memory card formats and solid-state drives available today. The hierarchical structure of NAND flash starts at a cell level which establishes strings, then pages, blocks, planes and ultimately a die. A string is a series of connected NAND cells in which the source of one cell is connected to the drain of
12972-529: The development of Neo Geo Pocket Color was discontinued after bankruptcy. Closely modeled after its predecessor , the Neo Geo Pocket Color design sports two face buttons on the right hand side of the system, and an eight-direction microswitched digital D-pad on the left. It is horizontally designed like the Game Gear , as opposed to the Game Boy 's vertical setup and the WonderSwan 's hybrid of both. Upgraded from
13110-443: The discontinuation of Neo Geo hardware and software there. The Neo Geo Pocket Color (and other SNK/Neo Geo products) did however, last until 2001 in Japan. It was SNK's last video game console, as the company went bankrupt on October 30, 2001. In June 2000, Aruze (parent of SNK) decided to discontinue all SNK operations outside Japan. As a result, remaining stock was bought back by SNK for repackaging in Asia. SNK were recalling most of
13248-573: The dominant memory type wherever a system required a significant amount of non-volatile solid-state storage . EEPROMs, however, are still used in applications that require only small amounts of storage, e.g. in SPD implementations on computer memory modules. Flash memory packages can use die stacking with through-silicon vias and several dozen layers of 3D TLC NAND cells (per die) simultaneously to achieve capacities of up to 1 tebibyte per package using 16 stacked dies and an integrated flash controller as
13386-575: The entire device. NOR flash memory allows a single machine word to be written – to an erased location – or read independently. A flash memory device typically consists of one or more flash memory chips (each holding many flash memory cells), along with a separate flash memory controller chip. The NAND type is found mainly in memory cards , USB flash drives , solid-state drives (those produced since 2009), feature phones , smartphones , and similar products, for general storage and transfer of data. NAND or NOR flash memory
13524-402: The first handheld electronic game with the release of Auto Race . Later, several companies—including Coleco and Milton Bradley —made their own single-game, lightweight table-top or handheld electronic game devices. The first commercial successful handheld console was Merlin from 1978, which sold more than 5 million units. The first handheld game console with interchangeable cartridges
13662-497: The first commercial NOR type flash chip in 1988. NOR-based flash has long erase and write times, but provides full address and data buses , allowing random access to any memory location . This makes it a suitable replacement for older read-only memory (ROM) chips, which are used to store program code that rarely needs to be updated, such as a computer's BIOS or the firmware of set-top boxes . Its endurance may be from as little as 100 erase cycles for an on-chip flash memory, to
13800-462: The flash storage device (such as SSD ), the data actually written to the flash memory may be 0011 1100. Vertical NAND (V-NAND) or 3D NAND memory stacks memory cells vertically and uses a charge trap flash architecture. The vertical layers allow larger areal bit densities without requiring smaller individual cells. It is also sold under the trademark BiCS Flash , which is a trademark of Kioxia Corporation (formerly Toshiba Memory Corporation). 3D NAND
13938-418: The floating gate. This is why data retention goes down and the risk of data loss increases with increasing degradation. The silicon oxide in a cell degrades with every erase operation. The degradation increases the amount of negative charge in the cell over time due to trapped electrons in the oxide and negates some of the control gate voltage, this over time also makes erasing the cell slower, so to maintain
14076-413: The game's small library for its quality and wide selection of genres, specifically titles such as SNK vs. Capcom: Card Fighters Clash , Sonic Pocket Adventure , Magical Drop and Pac-Man , and for the system's build quality being robust and well-built. Parish blamed the system's commercial failure on both SNK's large lack of retail presence and for Aruze acquiring the company in 2000, concluding
14214-435: The high Vpp voltage for all flash chips in an SSD with a single shared external boost converter. In spacecraft and other high-radiation environments, the on-chip charge pump is the first part of the flash chip to fail, although flash memories will continue to work – in read-only mode – at much higher radiation levels. In NOR flash, each cell has one end connected directly to ground, and
14352-415: The higher charged FG threshold voltage (V T2 ) by changing the FG charge. In order to read a value from the cell, an intermediate voltage (V I ) between V T1 and V T2 is applied to the CG. If the channel conducts at V I , the FG must be uncharged (if it were charged, there would not be conduction because V I is less than V T2 ). If the channel does not conduct at the V I , it indicates that
14490-534: The idea and instead release the Genesis Nomad , a handheld version of the Genesis , as the successor. The Watara Supervision was released in 1992 in an attempt to compete with the Nintendo Game Boy. The first model was designed very much like a Game Boy, but it is grey in color and has a slightly larger screen. The second model was made with a hinge across the center and can be bent slightly to provide greater comfort for
14628-477: The late 1990s, years after the Game Gear, Atari Lynx, and original Game Boy had been discontinued. During the time when technologically superior handhelds had strict technical limitations, batteries had a very low mAh rating since batteries with heavy power density were not yet available. Modern game systems such as the Nintendo DS and PlayStation Portable have rechargeable Lithium-Ion batteries with proprietary shapes. Other seventh-generation consoles, such as
14766-487: The market, Yokoi designed the series of LCD-based games to include a digital time display in the corner of the screen. For later, more complicated Game & Watch games, Yokoi invented a cross shaped directional pad or "D-pad" for control of on-screen characters. Yokoi also included his directional pad on the NES controllers, and the cross-shaped thumb controller soon became standard on game console controllers and ubiquitous across
14904-659: The microSD card has an area of just over 1.5 cm , with a thickness of less than 1 mm. NAND flash has achieved significant levels of memory density as a result of several major technologies that were commercialized during the late 2000s to early 2010s. NOR flash was the most common type of Flash memory sold until 2005, when NAND flash overtook NOR flash in sales. Multi-level cell (MLC) technology stores more than one bit in each memory cell . NEC demonstrated multi-level cell (MLC) technology in 1998, with an 80 Mb flash memory chip storing 2 bits per cell. STMicroelectronics also demonstrated MLC in 2000, with
15042-422: The new data must be copied to a new, erased page. If a suitable erased page is available, the data can be written to it immediately. If no erased page is available, a block must be erased before copying the data to a page in that block. The old page is then marked as invalid and is available for erasing and reuse. This is different from operating system LBA view, for example, if operating system writes 1100 0011 to
15180-414: The next one. Depending on the NAND technology, a string typically consists of 32 to 128 NAND cells. Strings are organised into pages which are then organised into blocks in which each string is connected to a separate line called a bitline. All cells with the same position in the string are connected through the control gates by a wordline. A plane contains a certain number of blocks that are connected through
15318-474: The nitride, leading to degradation. Leakage is exacerbated at high temperatures since electrons become more excited with increasing temperatures. CTF technology however still uses a tunneling oxide and blocking layer which are the weak points of the technology, since they can still be damaged in the usual ways (the tunnel oxide can be degraded due to extremely high electric fields and the blocking layer due to Anode Hot Hole Injection (AHHI). Degradation or wear of
15456-413: The number of bits increases, the number of possible states also increases and thus the cell is less tolerant of adjustments to programming voltages, because there is less space between the voltage levels that define each state in a cell. The process of moving electrons from the control gate and into the floating gate is called Fowler–Nordheim tunneling , and it fundamentally changes the characteristics of
15594-542: The original Game Boy. It can also give the sprites and backgrounds separate colors, for a total of more than four colors. The Neo Geo Pocket Color (or NGPC) was released in 1999 in Japan, and later that year in the United States and Europe. It is a 16-bit color handheld game console designed by SNK , the maker of the Neo Geo home console and arcade machine. It came after SNK's original Neo Geo Pocket monochrome handheld, which debuted in 1998 in Japan. In 2000 following SNK's purchase by Japanese Pachinko manufacturer Aruze,
15732-516: The other end connected directly to a bit line. This arrangement is called "NOR flash" because it acts like a NOR gate: when one of the word lines (connected to the cell's CG) is brought high, the corresponding storage transistor acts to pull the output bit line low. NOR flash continues to be the technology of choice for embedded applications requiring a discrete non-volatile memory device. The low read latencies characteristic of NOR devices allow for both direct code execution and data storage in
15870-444: The other, for an early 3D effect . In 1983, Takara Tomy 's Tomytronic 3D simulates 3D by having two LCD panels that were lit by external light through a window on top of the device, making it the first dedicated home video 3D hardware. The late 1980s and early 1990s saw the beginnings of the modern-day handheld game console industry, after the demise of the Microvision. As backlit LCD game consoles with color graphics consume
16008-435: The oxides is the reason why flash memory has limited endurance, and data retention goes down (the potential for data loss increases) with increasing degradation, since the oxides lose their electrically insulating characteristics as they degrade. The oxides must insulate against electrons to prevent them from leaking which would cause data loss. In 1991, NEC researchers including N. Kodama, K. Oyama and Hiroki Shirai described
16146-413: The performance and reliability of the NAND chip, the cell must be retired from use. Endurance also decreases with the number of bits in a cell. With more bits in a cell, the number of possible states (each represented by a different voltage level) in a cell increases and is more sensitive to the voltages used for programming. Voltages may be adjusted to compensate for degradation of the silicon oxide, and as
16284-541: The relationship between the bit line and the word lines resembles a NAND gate; in NOR flash, it resembles a NOR gate. Flash memory, a type of floating-gate memory, was invented by Fujio Masuoka at Toshiba in 1980 and is based on EEPROM technology. Toshiba began marketing flash memory in 1987. EPROMs had to be erased completely before they could be rewritten. NAND flash memory, however, may be erased, written, and read in blocks (or pages), which generally are much smaller than
16422-454: The relatively thin oxide, gradually degrading its electrically insulating properties and allowing electrons to be trapped in and pass through freely (leak) from the floating gate into the oxide, increasing the likelihood of data loss since the electrons (the quantity of which is used to represent different charge levels, each assigned to a different combination of bits in MLC Flash) are normally in
16560-410: The same bitline. A flash die consists of one or more planes, and the peripheral circuitry that is needed to perform all the read, write, and erase operations. The architecture of NAND flash means that data can be read and programmed (written) in pages, typically between 4 KiB and 16 KiB in size, but can only be erased at the level of entire blocks consisting of multiple pages. When a block is erased, all
16698-463: The same cardboard boxes, while all European releases used the clamshell cases. Towards the end of the system's short lifespan in North America, games were often bundled together in blister packs and sold in stores to clear out inventory, often including previously-unreleased titles such as Faselei! . Several Neo Geo Pocket Color games were re-released for the first time via emulation on Nintendo Switch , beginning with Samurai Shodown! 2 in 2019 as
16836-407: The same silicon nitride material. An individual memory cell is made up of one planar polysilicon layer containing a hole filled by multiple concentric vertical cylinders. The hole's polysilicon surface acts as the gate electrode. The outermost silicon dioxide cylinder acts as the gate dielectric, enclosing a silicon nitride cylinder that stores charge, in turn enclosing a silicon dioxide cylinder as
16974-408: The system during usage. The Neo Geo Pocket Color has no regional lockout . The system has an on-board language setting, and games display text in the language selected (provided the cartridge supports that language). Other settings include time and date, and the system can provide customized horoscopes when one's birth date is entered. Cables for linking multiple systems were available, as well as
17112-586: The system every year until 2004's Winter Games . The TurboExpress is a portable version of the TurboGrafx, released in 1990 for $ 249.99. Its Japanese equivalent is the PC Engine GT . It is the most advanced handheld of its time and can play all the TurboGrafx-16 's games (which are on a small, credit-card sized media called HuCards ). It has a 66 mm (2.6 in.) screen, the same as the original Game Boy, but in
17250-520: The system had a decent market debut, competition against Nintendo 's Game Boy Color was tough, and ultimately Neo Geo Pocket Color sales were not as good. The system was discontinued in the West by mid-2000, and continued to be marketed in Japan until SNK's bankruptcy in October 2001. Despite being a commercial failure, the platform has been well regarded for a number of highly-acclaimed exclusive games derived from
17388-516: The system's early defeat in the handheld market, saying: "It was a premature end for a system that, although doomed to remain a distant second to the Game Boy, could have forged a great little niche of its own." NintendoLife ' s Damien McFerran said that both it and the WonderSwan served as some of the most "interesting challengers" towards Nintendo. He commended the system for its game library and clamshell boxes, hardware capabilities, battery life and lasting legacy on future systems, writing: "Like
17526-418: The tunnel dielectric that surrounds a central rod of conducting polysilicon which acts as the conducting channel. Memory cells in different vertical layers do not interfere with each other, as the charges cannot move vertically through the silicon nitride storage medium, and the electric fields associated with the gates are closely confined within each layer. The vertical collection is electrically identical to
17664-446: The two games were so successful that according to Katz, "these simple electronic handheld games turned into a '$ 400 million category.'" Mattel would later win the honor of being recognized by the industry for innovation in handheld game device displays. Soon, other manufacturers including Coleco , Parker Brothers , Milton Bradley , Entex , and Bandai began following up with their own tabletop and handheld electronic games. In 1979
17802-447: The user. While the system did enjoy a modest degree of success, it never impacted the sales of Nintendo or Sega. The Supervision was redesigned a final time as "The Magnum". Released in limited quantities it was roughly equivalent to the Game Boy Pocket . It was available in three colors: yellow, green and grey. Watara designed many of the games themselves, but did receive some third party support, most notably from Sachen . A TV adapter
17940-593: The video game industry since. When Yokoi began designing Nintendo's first handheld game console, he came up with a device that married the elements of his Game & Watch devices and the Famicom console, including both items' D-pad controller. The result was the Nintendo Game Boy. In 1982, the Bandai LCD Solarpower was the first solar-powered gaming device. Some of its games, such as the horror -themed game Terror House , features two LCD panels , one stacked on
18078-419: The zooming and scaling of sprites. The Lynx can also be turned upside down to accommodate left-handed players. However, all these features came at a very high price point, which drove consumers to seek cheaper alternatives. The Lynx is also very unwieldy, consumes batteries very quickly, and lacked the third-party support enjoyed by its competitors. Due to its high price, short battery life, production shortages,
18216-536: Was available in both PAL and NTSC formats that could transfer the Supervision's black-and-white palette to 4 colors, similar in some regards to the Super Game Boy from Nintendo. The Hartung Game Master is an obscure handheld released at an unknown point in the early 1990s. Its graphics fidelity was much lower than most of its contemporaries, displaying just 64x64 pixels. It was available in black, white, and purple, and
18354-417: Was first announced by Toshiba in 2007. V-NAND was first commercially manufactured by Samsung Electronics in 2013. V-NAND uses a charge trap flash geometry (which was commercially introduced in 2002 by AMD and Fujitsu ) that stores charge on an embedded silicon nitride film. Such a film is more robust against point defects and can be made thicker to hold larger numbers of electrons. V-NAND wraps
18492-601: Was frequently rebranded by its distributors, such as Delplay, Videojet and Systema. The exact number of games released is not known, but is likely around 20. The system most frequently turns up in Europe and Australia. By this time, the lack of significant development in Nintendo 's product line began allowing more advanced systems such as the Neo Geo Pocket Color and the WonderSwan Color to be developed. The Nomad
18630-551: Was horizontal in orientation and like the Game Boy, required 4 AA batteries. Unlike many later Game Boy clones, its internal components were professionally assembled (no "glop-top" chips). Unfortunately the system's fatal flaw is its screen. Even by the standards of the day, its screen is rather difficult to use, suffering from similar ghosting problems that were common complaints with the first generation Game Boys. Likely because of this fact sales were quite poor, and Bitcorp closed by 1992. However, new games continued to be published for
18768-533: Was not a new software platform and played the same software as the original Game Boy model. The Game.com (pronounced in TV commercials as "game com", not "game dot com", and not capitalized in marketing material) is a handheld game console released by Tiger Electronics in September 1997. It featured many new ideas for handheld consoles and was aimed at an older target audience, sporting PDA-style features and functions such as
18906-501: Was released in October 1995 in North America only. The release was six years into the market span of the Genesis, with an existing library of more than 500 Genesis games. According to former Sega of America research and development head Joe Miller, the Nomad was not intended to be the Game Gear's replacement; he believed that there was little planning from Sega of Japan for the new handheld. Sega
19044-586: Was supporting five different consoles: Saturn , Genesis, Game Gear , Pico , and the Master System , as well as the Sega CD and 32X add-ons. In Japan, the Mega Drive had never been successful and the Saturn was more successful than Sony's PlayStation , so Sega Enterprises CEO Hayao Nakayama decided to focus on the Saturn. By 1999, the Nomad was being sold at less than a third of its original price. The Game Boy Pocket
