Abstract

PURPOSE: To decrease the bit width of the register by detecting the fault of the storage address based on the reading data given from the memory device and the contents of the error correction code storage register.
CONSTITUTION: The error correction code is generated 5 from writing data WD to memory device 3 and then stored 6. While address register 10 and address holding register 11 are provided at the access control part in the same number of units as error correction code storage register 6. Then at least one storage address is designated in device 3 to store the writing data, and the error correction code concerning the writing data is stored in register 6. Then storage address is designated, and the fault is detected 9 for the storage address based on the reading data read out and the contents of register 6.
