The MultiMediaCard (MMC) is a memory card standard used for solid-state storage. Unveiled in 1997 by SanDisk and Siemens AG, it is based on Toshiba 's NAND-based flash memory, and is therefore much smaller than earlier systems based on Intel NOR-based memory such as CompactFlash.MC is about the size of a postage stamp: 24 mm Ã 32 mm Ã 1.4 mm. MMC originally used a 1- bit serial interface, but newer versions of the specification allow transfers of 4 or 8 bits at a time. MMC can be used in most devices that can use SD cards.
