Abstract

A control device, which controls access to the data stored in a memory device, includes a selector, a changing unit, a notification unit, and a power supply controller. When the number of accesses to a memory device is out of a range of a predetermined threshold, the selector selects a piece of data from pieces of data controlled by the control device itself or another control device. The changing unit changes a control device for controlling access to the selected a piece of data. The notification unit notifies an information processing device of a control device after changed and the selected a piece of data to be controlled by the control device after changed. The power supply controller controls a power supply of the control device after changed or a power supply of a control device that has controlled access to the selected a piece of data.
