MultiMediaCard (MMC) was a flash memory memory card format introduced in 1997 by SanDisk and Siemans.
Although superseded by Secure Digital (SD), MultiMediaCard can be used in most devices that support SD, as MMC is pin-compatible (although slightly thinner).
Smaller variants of MMC are Reduced-Size MultiMediaCard (RS-MMC) and MMCmicro.
By 2006, SanDisk no longer sold the MultiMediaCard format.
