Definitions for "MultiMediaCard"
A form of removable flash memory, MultiMediaCards (or MMCs) were developed by SanDisk and are supported by several A/V manufacturers for a variety of uses. Like other flash memory cards, they are small (about the size of a postage stamp), durable, provide solid-state memory and fast read/write speeds, and are available in a range of capacities. (They also share the higher prices of other kinds of flash memory.) MMCs may be gradually supplanted by another form of digital storage called SD ( Secure Digital) memory, which features SDMI compliance for copyright protection. However, SD devices have backward compatibility, so you will be able to use your existing MMC media in a player that accepts SD cards and does not have copy protection requirements.
