Micro SD Memory Card

The MicroSD format was originally called T-Flash, and then TransFlash, before being renamed MicroSD when adopted by the SD Card Association (SDA). At 15 mm x 11 mm x 1.0 mm it is currently the smallest memory card format available. It is one of the smallest removable flash memory card formats designed specifically for mobile phones and other small devices. When used with its adapter, it is also compatible with all Secure Digital devices.
