MultiMediaCard: Flash memory memory card standard. Unveiled in 1997 by Siemens AG and SanDisk. Free documentation as opposed to SD-Card standard. Which sandisk.com doesn't follow anywayTemplate:Fact.

Many projects at OpenCircuits use the MMC protocol to talk to a flash memory card (even when that card is actually a SD card). These include the Minimig Project and many of the Music Player projects.
