JEIDA 4.1
The JEIDA memory card standard is a popular memory card standard at the beginning of memory cards appearing on portable computers. JEIDA cards could be used to expand system memory or as a solid-state storage drive. History Before the advent of the JEIDA standard, laptops had proprietary cards that were not interoperable with other manufacturers laptops, other laptop lines, or even other models in the same line. The establishment of the JEIDA interface and cards across Japanese portables provoked a response from the US government, through SEMATECH, and thus PCMCIA was born. PCMCIA and JEIDA worked to solve this rift between the two competing standards, and merged into JEIDA 4.1 or PCMCIA 2.0 in 1991. Usage The JEIDA memory card was used in earlier ThinkPad models, where IBM branded them as IC DRAM Cards. The interface has also been used for SRAM cards. Versions *Version 1.0 is an 88-pin memory card. It has 2 rows of pin holes which are shifted against each other by hal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ThinkPad 360PE IC DRAM
ThinkPad is a line of business-oriented laptop computers and tablets designed, developed and marketed by Lenovo, and formerly by IBM until 2005, when IBM's PC business was acquired by Lenovo. ThinkPads have a distinct black, boxy design language, inspired by a Japanese ''bento'' lunchbox, which originated in 1990 and is still used in some models. Most models also feature a red-colored trackpoint on the keyboard, which has become an iconic and distinctive design characteristic associated with the ThinkPad line. The ThinkPad line was first developed at the IBM Yamato Facility in Japan, and the first ThinkPads were released in October 1992. It has seen significant success in the business market. ThinkPad laptops have been used in outer space and for many years were the only laptops certified for use on the International Space Station. ThinkPads have also for several years been one of the preferred laptops used by the United Nations. History The ThinkPad was developed to co ...

SEMATECH
SEMATECH (from Semiconductor Manufacturing Technology) is a not-for-profit consortium that performs research and development to advance chip manufacturing. SEMATECH has broad engagement with various sectors of the R&D community, including chipmakers, equipment and material suppliers, universities, research institutes, and government partners. The group is funded by member dues. History SEMATECH was conceived in 1986, formed in 1987, and began operating in Austin, Texas in 1988 as a partnership between the United States government and 14 U.S.-based semiconductor manufacturers to solve common manufacturing problems and regain competitiveness for the U.S. semiconductor industry that had been surpassed by Japanese industry in the mid-1980s. SEMATECH was funded over five years by public subsidies coming from the U.S. Department of Defense via the Defense Advanced Research Projects Agency (DARPA) for a total of $500 million. Following a determination by SEMATECH Board of Directors ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Personal Computer Memory Card International Association
The Personal Computer Memory Card International Association (PCMCIA) was a group of computer hardware manufacturers, operating under that name from 1989 to 2009. Starting with the PCMCIA card in 1990 (the name later simplified to ''PC Card''), it created various standards for peripheral interfaces designed for laptop computers. History The PCMCIA (Personal Computer Memory Card International Association) industry organization was based on the original initiative of the British mathematician and computer scientist Ian H. S. Cullimore, one of the founders of the Sunnyvale-based Poqet Computer Corporation, who was seeking to integrate some kind of memory card technology as storage medium into their early DOS-based palmtop PCs, when traditional floppy drives and harddisks were found to be too power-hungry and large to fit into their battery-powered handheld devices. When in July 1989, Poqet contacted Fujitsu for their existing but still non-standardized SRAM memory cards, and Int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Static Random-access Memory
Static random-access memory (static RAM or SRAM) is a type of random-access memory (RAM) that uses latching circuitry (flip-flop) to store each bit. SRAM is volatile memory; data is lost when power is removed. The term ''static'' differentiates SRAM from DRAM (''dynamic'' random-access memory) — SRAM will hold its data permanently in the presence of power, while data in DRAM decays in seconds and thus must be periodically refreshed. SRAM is faster than DRAM but it is more expensive in terms of silicon area and cost; it is typically used for the cache and internal registers of a CPU while DRAM is used for a computer's main memory. History Semiconductor bipolar SRAM was invented in 1963 by Robert Norman at Fairchild Semiconductor. MOS SRAM was invented in 1964 by John Schmidt at Fairchild Semiconductor. It was a 64-bit MOS p-channel SRAM. The SRAM was the main driver behind any new CMOS-based technology fabrication process since 1959 when CMOS was invented. In 1965, ...

Neo Geo (console)
The , stylised as NEO•GEO and also written as NEOGEO, is a cartridge-based arcade system board and the fourth generation home video game console released on April 26, 1990 by Japanese game company SNK Corporation. It was the first system in SNK's Neo Geo family. The Neo Geo was marketed as the first 24-bit; its CPU is technically a 16/ 32-bit 68000-based system with an 8-bit Z80 coprocessor, while its GPU chipset has a 24-bit graphics data bus. The Neo Geo originally launched as the MVS (Multi Video System) coin-operated arcade machine. The MVS offers owners the ability to put up to six different cartridges into a single cabinet, a unique feature that was also a key economic consideration for operators with limited floorspace, as well as saving money long-term. With its games stored on self-contained cartridges, a game cabinet can be exchanged for a different game title by swapping the game's ROM cartridge and cabinet artwork. A home console version was also made, ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

PC Card
In computing, PC Card is a configuration for computer parallel communication peripheral interface, designed for laptop computers. Originally introduced as PCMCIA, the PC Card standard as well as its successors like CardBus were defined and developed by the Personal Computer Memory Card International Association (PCMCIA). It was originally designed as a standard for memory- expansion cards for computer storage. The existence of a usable general standard for notebook peripherals led to many kinds of devices being made available based on their configurability, including network cards, modems, and hard disks. History The PCMCIA 1.0 card standard was published by the Personal Computer Memory Card International Association in November 1990 and was soon adopted by more than eighty vendors. It corresponds with the Japanese JEIDA memory card 4.0 standard. SanDisk (operating at the time as "SunDisk") launched its PCMCIA card in October 1992. The company was the first to introduce ...
