MMC - Multimedia Cards
Multimedia card memory (abbreviated as MMC) is a type of memory card created jointly by SanDisk and Siemens in November 1997.
Its architecture is based on a combination of read-only memory (ROM) for read-only applications and flash memory for read/write purposes.
Multimedia cards are very small (24.0 mm x 32.0 mm x 1.4 mm), which is equivalent to the size of a postage stamp, and weigh only 2.2 grams.
There are two types of MMC cards that have different voltages:
- MMC 3.3V, with a notch on the upper left-hand corner
- MMC 5V, with a notch on the upper right-hand corner
Data can be accessed by way of an edge connector with 7 pins, for a throughput of up to 2 Mb/s (perhaps even 2.5 Mb/s).
