Mini SD Memory Card
Logically and electrically, the MiniSD Memory Card and the SD Memory Card are identical. Only the form factor, size, and number of pins of the MiniSD Memory Card are different from the standard SD Memory Card. The MiniSD Card was designed to meet a special requirement from some of the mobile phone companies for the smallest possible memory card size. With an adapter, a MiniSD card can be used as a regular size SD card.
