The Personal Computer Memory Card International Association (PCMCIA) was an industry consortium of computer hardware manufacturers 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.
Before the introduction of the PCMCIA card, the parallel port was commonly used for portable peripherals. [6] 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. [7] [8] It corresponds with the Japanese JEIDA memory card 4.0 ...
As PC Cards (was PCMCIA), Linear Flash cards should have a Card Information Structure (CIS). However, many memory cards do not have a CIS. However, many memory cards do not have a CIS. Linear Flash cards begin to develop bad blocks after about 100,000 erase/write cycles and thus are of dubious value on the second-hand market.
The number of compatible memory cards varies from reader to reader and can include more than 20 different types. The number of different memory cards that a multi card reader can accept is expressed as x-in-1, with x being a figure of merit indicating the number of memory cards accepted, such as 35-in-1. There are three categories of card ...
The specification for PCMCIA type I cards, later renamed PC Cards, was first released in 1990, and unified the JEIDA memory card standard with the PC Card standard. [ 15 ] [ 17 ] This format later included support for other devices besides memory cards. [ 17 ]
Originally developed by the Personal Computer Memory Card International Association (), the ExpressCard standard is maintained by the USB Implementers Forum ().The host device supports PCI Express, USB 2.0 (including Hi-Speed), and USB 3.0 (SuperSpeed) [2] (ExpressCard 2.0 only) connectivity through the ExpressCard slot; cards can be designed to use any of these modes.
Original PC Card memory cards used an internal battery to maintain data when power was removed. The rated life of the battery was the only reliability issue. CompactFlash cards that use flash memory, like other flash-memory devices, are rated for a limited number of erase/write cycles for any "block."
P2 (P2 is a short form for "Professional Plug-In") is a professional digital recording solid-state memory storage media format introduced by Panasonic in 2004. The P2 card is essentially a RAID of Secure Digital (SD) memory cards with an LSI controller tightly packaged in a die-cast PC Card (formerly PCMCIA) enclosure.
