PROBLEM TO BE SOLVED: To provide a technique for rewriting data to a non-volatile memory with a simple configuration.SOLUTION: Rewriting means (S125) executes rewrite by reading data in a rewrite region with a predetermined size in a non-volatile memory and writing the read data into the non-volatile memory again. Address reading means (S110) reads a start determination physical address which is a physical address for determining a start position of rewriting in the non-volatile memory out of a management information region where a physical address can be specified in the non-volatile memory. Address writing means (S170) writes the physical address for determining a start position of next rewriting in the management information region as a start determination physical address after completion of rewriting by the rewriting means (S140; YES).SELECTED DRAWING: Figure 4 |
