PROBLEM TO BE SOLVED: To improve the reliability of a memory device by decreasing physical burdens on memory elements as much as possible.SOLUTION: In a memory element arrangement part, a plurality of memory elements capable of storing M value data are arranged. Out of the first data to M-th data constituting the M value data, the M-th data are held by the memory element in an erasure state before write-in operation is performed for the memory element, in the first data, the physical burdens applied to the memory elements for writing are the largest out of the M-th value data. A data processing part specifies the minimum number data in which a number included in the conjugation of write-in data is the minimum when the minimum number data are other than the first data, the minimum number data included in the conjugation of the write-in data are replaced with the first data while the first data included in the assembly of the write-in data are replaced with the minimum number data. |
