Sign in to saveAlso known as MMC, MMC card, MMCmobile, MMC mobile
MultiMediaCard (MMC) is a memory card standard used for solid-state storage, originally introduced in 1997 by SanDisk, Siemens, and Nokia. Designed as a compact, low-pin-count, postage‑stamp‑sized card alternative to earlier storage solutions, MMC uses a serial interface and a single memory stack assembly, making it smaller and simpler than high-pin-count, parallel-interface cards such as CompactFlash, which was previously developed by SanDisk.

MultiMediaCard (MMC) is a memory card standard used for solid-state storage, originally introduced in 1997 by SanDisk, Siemens, and Nokia. Designed as a compact, low-pin-count, postage‑stamp‑sized card alternative to earlier storage solutions, MMC uses a serial interface and a single memory stack assembly, making it smaller and simpler than high-pin-count, parallel-interface cards such as CompactFlash, which was previously developed by SanDisk.
It has since evolved into several variants, including the widely used SD card and the eMMC (embedded MMC) which is soldered directly onto a device's circuit board. While removable MMC cards have largely been supplanted by SD cards, eMMC remains common in low-cost smartphones, tablets, and budget laptops due to its compact size and affordability, despite being slower and less upgradeable than modern solid-state drives.
