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.
