MEMORY MANAGEMENT DEVICE

摘要

Disclosed is a memory management device (1) that controls, corresponding to a write request and a readout request from a processor (6a), write and readout on and from main storage memory (2), which includes nonvolatile semiconductor memory (9) and volatile semiconductor memory (8). The memory control device (1) is provided with: a coloring information storage unit (17), which holds coloring information (14) generated based on the data characteristics of data to be written on the nonvolatile semiconductor memory (9) and/or the volatile semiconductor memory (8); and a write management unit (15), which refers to the coloring information (14) and determines a region in which the data to be written is to be written in the nonvolatile semiconductor memory (9) and the volatile semiconductor memory (8).
