<P>PROBLEM TO BE SOLVED: To shorten a data transfer processing time between a memory card and a host device. <P>SOLUTION: A memory card includes a register circuit 13, a data buffer circuit 14, a memory I/F controller 16, and a flash memory 17. An access to the register circuit 13 and the data buffer circuit 14 is gained from the host device using a command (TPC) determined on a transfer protocol. An expansion command for simultaneously transferring parameter stored in the register circuit 13 and a control instruction given to a memory I/F controller 16 is set in the TPC. <P>COPYRIGHT: (C)2003,JPO |
