摘要

A multi-functional mini-memory card serves for storing data and support data input and output. The multi-functional mini-memory card comprises a memory card I/O functional module; a memory for storing data; and a main controller connecting between the memory card I/O functional module and the memory. The input/output port of the multi-functional mini-memory card have eight joints, four of the eight joint is used for USB interface, and all eight joints are used for an SFMI interface. The power source joint and ground joint of the SFMI interface are identical to the power source joint and the ground joint of the USB interface, respectively. A multi-functional mini-memory card slot has eight joints, wherein four of the eight joints are suitable for USB interface and all the eight joints suitable for an SFMI interface. The joint may be male joint or female joint.
