Zusammenfassung:PROBLEM TO BE SOLVED: To provide a memory control device for controlling a memory so as to improve the reliability of data to be stored in the memory. SOLUTION: A block area determination part 31 determines an area accessed in a plurality of areas of an MRAM. An access frequency counter updating part 32 counts non-access frequency for each plurality of areas, based on area information determined by the block area determination part 31. A refresh area determination part 33 determines an area to be refreshed according to the non-access frequency counted for each plurality of areas by the access area counter updating part 32. Thereby, error data can be corrected and rewritten before data correction is disabled, and the reliability of data to be stored in the MRAM can be improved. COPYRIGHT: (C)2011,JPO&INPIT
