PROBLEM TO BE SOLVED: To provide a function for detecting an error in each of a plurality of semiconductor memory units and correcting corrupted data.SOLUTION: A function stores data 240, 241, 242, and 243 in first semiconductor memory units 210, 211, 212, and 213 and stores error correction information 244 in a second semiconductor memory unit 214 to recover the data. The error correction information has a value equal to at least a value of the data stored in the first memory units. |
