ABSTRACT:
An IC memory card has a byte rewriting type EEPROM implementing a supervisory area for storing supervisory data which should be rewritten byte by byte, and a flushing type EEPROM implementing a data area for storing picture data or similar data which are usually generated in a great amount. When an address for writing data in the supervisory area is sent from a host processor to the card, an address identifying section determines the value of the address and activates a memory controller to write the data in the supervisory area. When an address for writing picture data is sent from the host processor, the address identifying section determines the value of the address and activates another memory controller associated with the data area to thereby write the picture data in the data area.
