A PC card is provided through which data can be read and written at a high speed. When a system main unit reads data of one sector from a flash memory of the PC card, the relevant data of one sector from among the data of one block including the relevant data is written in a first RAM, and data of the other sectors is written in a second RAM. Since the system main unit can perform data input/output between it and the high-speed first RAM, the reading and writing speed of data is increased. If the first RAM is contained in a control apparatus and the data is allocated to the first RAM and the second RAM on the basis of the value of the register, it is possible to perform data input/output with ease.
