PROBLEM TO BE SOLVED: To provide a memory management device for improving the hit rate of a cache memory when a non-volatile semiconductor memory is used as a main memory. SOLUTION: Non-volatile semiconductor memories (9, 10) store data. A volatile semiconductor memory (8) includes a plurality of areas, some of which are used as cache memories of the non-volatile semiconductor memory. A control part (1) determines an area to arrange the data from among the plurality of areas of the volatile semiconductor memory, based on layout hint information generated based on the characteristics of the data written on the non-volatile semiconductor memory or the volatile semiconductor memory and giving a hint for determining a data layout area on the non-volatile semiconductor memory or the volatile semiconductor memory.
