Video game consoles

PlayStation memory card

Video game consoles use memory cards to hold saved game data. Cartridge-based systems primarily used battery-backed RAM within each individual cartridge to hold saves for that game. The Neo Geo AES, released in 1990 by SNK, was the first video game console able to use a memory card. AES memory cards were also compatible with Neo-Geo MVS arcade cabinets, allowing players to migrate saves between home and arcade systems and vice versa. Memory cards became commonplace when home consoles moved to read-only optical discs for storing the game program, beginning with systems such as the TurboGrafx-CD and Mega-CD.

Until the sixth generation of video game consoles, memory cards were based on proprietary formats; later systems have used established industry hardware formats for memory cards.

Home consoles now commonly use hard disk drive storage for saved games. though most portable gaming systems still rely on custom memory cartridges to store program data, due to their low power consumption, smaller physical size and reduced mechanical complexity.
