Zusammenfassung:PROBLEM TO BE SOLVED: To perform error detection and correction processing by the use of error correcting codes suited to an access size without straining the storage capacity of a nonvolatile memory.SOLUTION: A first error detection unit is configured to execute error detection in accordance with a first data unit read from a memory and a first error detection code corresponding to the first data unit. A second error detection unit is configured, if a second error detection code corresponding to a second data unit smaller than the first data unit is held in an error detection code hold unit different from the memory, to execute error detection in accordance with the second data unit read from the memory and the second error detection code held in the error detection code hold unit.
