ABSTRACT:
A memory card integrating functions of the USB interface includes a memory chip inside a main body. A SD or MS control interface, a USB control interface, a controller, and a storage memory are built in the memory chip. Conductive bars are electrically connected to the memory chip and stick out from one end of the main body. An adaptor for the memory card includes an insertion socket to receive a SD memory card or a MS memory card. Conductive pins are positioned inside the insertion socket to be electrically connected to the memory card. A USB connecting head is provided at the front end of the insertion socket and electrically connected to the conductive pins inside the insertion socket. The SD memory card and the MS memory card can be inserted into the USB slot through the adaptor.
