A communication protocol for multi-functional mini-memory cards is disclosed. Data is transferred through semi-duplex process and four bitstreams of data being transferred in parallel. A CLK signal is used as a base clock in data transfer. Each clock has four bits of data being transferred in parallel. In each bitstream, data is transferred as data packages. Endpoints are used as the data source and data sink in a transmitting end and a receiving end, respectively. A data package includes start bits, package identification codes, communication endpoints; data length, payloads, package status codes, data formats; and end bits.

Communication protocol for multi-functional mini-memory card suitable for small form memory interface and usb interfaces

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.
