A MultiMediaCard (MMC) is a type of memory card used for storing data in various electronic devices, such as cameras, smartphones, and tablets. It was introduced in 1997 and is designed to be compact and lightweight, making it easy to use in portable devices. MMCs are available in different storage capacities, allowing users to choose the right amount of space for their needs. The MMC operates using flash memory technology, which enables quick data access and transfer. It is similar to other memory cards, like Secure Digital (SD) cards, but has its own specifications and compatibility requirements. Over time, MMCs have evolved, leading to the development of enhanced versions like MMCplus and MMCmobile.
