Abstract

This invention provides a memory card device using an EEPROM as a semiconductor memory. When a data write-in defective area is detected in the storage area of the EEPROM, a space area is retrieved from the storage area of the EEPROM as a relieving area and data to be written into the data write-in defective area is written into the relieving area. Then, when the relieving area becomes full and a data write-in defective area is detected in the storage area of the EEPROM, another space area is retrieved from the storage area of the EEPROM as a new relieving area and data to be written into the data write-in defective area is written into the new relieving area.
