Abstract
A universal micro memory card has a unique common transmission interface designed according to USB specifications, USB pins and data transmission pins. The universal micro card detects what type a system interface connected to it is and the initialization signals are sent from the system end via the USB pins (D+ and D−). Further, the universal micro card is switched to the corresponding working mode. In this way, the universal micro memory card enables signal transmission from/to different memory card systems via the common transmission interface.
