Histori

PC Card (PCMCIA) is the first commercial memory card format (type I card) that will come out, but is now primarily used in industrial applications and for connecting I/O devices such as modems. Since 1994, a number of smaller memory card formats from PC Cards have arrived, the first being CompactFlash and then SmartMedia and Miniature Card. The desire for smaller cards for mobile phones, PDAs and compact digital cameras is driving the trend that makes the previous generation's "compact" cards look great. In digital cameras, SmartMedia and CompactFlash are very successful. In 2001, SM alone seized 50% of the digital camera market and CF has seized the professional digital camera market. But in 2005, SD/MMC almost took over SmartMedia's position, though not at the same level and with fierce competition coming from the Memory Stick variant, as well as CompactFlash. In industry and embedded, even PC memory cards (PCMCIA) noble cards can still maintain a niche, while in mobile phones and PDAs, memory cards are becoming smaller.

Since 2010, Sony's new product (previously only using Memory Stick) and Olympus (previously only using XD-Card) have been offered with additional SD-Card slot. Effectively format war has changed the SD-Card support.

Video game console

Many older video game consoles use memory cards to store stored game data. Cartridge-based systems primarily use the battery-backed volatile RAM in each individual cartridge to store deposits for that game. These RAM-less cartridges may use a password system, or will not save any progress at all. Neo Geo AES, released in 1990 by SNK, is the first video game console to use a memory card. The AES memory card is also compatible with the Neo-Geo MVS arcade cabinet, allowing players to migrate saves between home and arcade systems and vice versa. Memory cards become commonplace when home consoles move to read-only optical discs to store game programs, starting with systems like TurboGrafx-CD and Sega-CD.

Until the sixth generation of video game consoles, memory cards are based on proprietary formats; then the system uses a ready-made industrial hardware format for memory cards, such as FAT32.

Home consoles now typically use hard disk drive storage for stored games and allow the use of generic USB flash drives or other card formats through memory card readers to transport game storage and other game information, along with cloud storage savings, although most portable game systems are still rely on special memory cartridges to store program data, due to low power consumption, smaller physical size and reduced mechanical complexity.
