STORAGE DEVICE HAVING NONVOLATILE STORAGE DEVICE

PROBLEM TO BE SOLVED: To quickly repair error data caused by unexpected power interruption remaining in data stored in a nonvolatile storage device which causes destructive read in data readout, without requiring a special hardware configuration. SOLUTION: In the storage area of an FeRAM 11, a user data area 111 and a block address area 112 are secured. The block address area 112 is used to store address data indicating the address where data to be read is stored when data is read out from the user data area 111. An MPU 16 serves to detect an error in data stored in the storage location of the user data area 111 indicated by the address data stored in the block address area 112, and if detecting an error, corrects the error data and writes the corrected data to the user data area 111.
