MEMORY MANAGEMENT SYSTEM AND PROGRAM

PROBLEM TO BE SOLVED: To reduce power consumption of a computer or the like.SOLUTION: A nonvolatile memory divided into a plurality of segments is applied to main memory used for virtual storage management. Power supply to the plurality of segments is stopped as appropriate. In this case, even in the presence of a physical address that is being used for a specific segment, code or data held in the physical address does not be lost. As a result, power consumption of the computer or the like for virtual storage management can be reduced without causing operation delay.
