PROBLEM TO BE SOLVED: To make possible local interruption of power supply to memories in an idle state.SOLUTION: An information processing device comprising multiple memories or multiple memory groups mounted in the same memory bus is equipped with means to shift, when the information processing device is in an idle state in which the multiple memories or the multiple memory groups are in an operating state but no job to be executed exists, the multiple memories or the multiple memory groups from the operating state to a self-refreshing state; means to interrupt, when the multiple memories or the multiple memory groups are in the self-refreshing state, power supply to a part of the multiple memories or the multiple memory groups; and means to shift, the multiple memories or the multiple memory groups except the part exempt from the interruption, from the self-refreshing state to the operating state.SELECTED DRAWING: Figure 3 |
