<p>PROBLEM TO BE SOLVED: To obtain a power-saving memory management system which can reduce unnecessary power consumption by connecting the power source when a request to refer to a powered-off storage area is made and re-setting the contents of a storage area to which the power begins to be supplied again as required. SOLUTION: A powered-off area reference detection part 2a judges whether or not a storage area which is powered-off is accessed by a program and reports the storage area when the area is accessed. A storage area power-source connection part 2b deletes the off flag of the storage area, which is reported from the reference detection part 2a and should be powered on again, in a powered off area management table TBL and turns on the corresponding power switch 4, and instructs a re-setting part 2c to re-set the contents of the storage area which beings to be powered on. The re-setting part 2c re-sets the contents of the indicated storage area. Therefore, unnecessary power consumption can be avoided.</p> |
