<p>PURPOSE:To provide a flush type EEPROM where the defect/deterioration information are written before these information are delivered to the users. CONSTITUTION:The defect/deterioration information on a flush type EEPROM 1 are written in an erasing block 000 of the EEPROM 1. Therefore a device containing the EEPROM 1 reads first the defect/deterioration information out of the block 000 and sets again an address that has an access to the EEPROM 1 to exclude the addresses of the defect/deterioration parts. In such a constitution, the device can use the EEPROM 1 even if the device has no ability to check the defect/deterioration parts of the EEPROM 1.</p> |
