ABSTRACT:
A semiconductor memory card1includes a user data area21and a management information area22, in a data storing unit2. According to a writing test command from a memory access device6, a memory controller3writes data into a user data storing area and measures the writing rate, and transmits the measurement result to the memory access device6via a host interface unit4. Thereby, the memory access device6can recognize the writing rate.
