MMCmicro

The MMCmicro, formerly known as S-CARD introduced by Samsung, was adopted and introduced in 2005 by the MultiMediaCard Association (MMCA) as the third form factor memory card in the MultiMediaCard family. MMCmicro is the smallest, about the size of a fingernail, memory card in the MultiMediaCard family and among the smallest in the world. It was specifically designed for being used in mobile phones and other small portable devices.

The MMCmicro memory card is available with an adaptor, MMCplus. This makes it not only compatible to all MMC and MMCplus slots but also to all SD Memory Card slots. It is important to keep in mind that music stored on MultiMediaCards my not be able to play back when inserted into a SD Memory Card slot due to the copyright protection features supported by the SD slots.

Since the MMCmicro is the latest memory card to be developed and introduced to the market it is not that compatible to many mobile phones and electronic devices yet. Still it is expected to be one of the memory card formats that will dominate in the mobile phone industry among the frontrunner microSD and the under development Memory Stick Micro.

The miniSD was introduced in 2003 by SanDisk Corporation in cooperation with Matsushita (Panasonic) and Toshiba. Later in that year the miniSD format was adapted by the SD Card Association as the second form factor memory card in the Secure Digital family. MiniSD is a smaller version of the SD memory Card format, about 60% smaller in volume, and offers the same benefits as the SD Memory Card expect of the writing protection switch.

MiniSD was designed specifically to be used in small portable electronic devices like digital cameras and mobile phones. But since all miniSD memory cards always come with a SD Memory Card adaptor, they are compatible to all SD Memory Card slots and thereby provide compatibility with the rapidly growing number of SD Memory Card compatible devices in the market.

MiniSD was the second, after SD Memory Card, memory card to be adapted by the SD Card Association, which today consists of three members. In 2005 the microSD was introduced as the third, and smallest, member of the Secure Digital family.
