ABSTRACT:
A comparing unit (12) in a readout control unit (11) compares one bit data stored in a memory body (20) with a value stored in a data storage unit B[m] which is prepared to store the one bit data. The data storage unit B[m] includes three memory cells MC[k] and the stored value of the data storage unit B[m] is obtained by a logical operation unit (16) operable to calculate an exclusive OR with respect to the three memory cells MC[k]. When mismatching is detected in the comparing unit (12), a rewrite cell determination unit (13) determines one of the three memory cells MC[k], to which rewriting of the stored value is performed. In the case where the stored value in the data storage unit B[m], if the data storage unit B[m] has a memory cell MC[k] to which writing can be performed, the writing is performed in priority to erasing.
