<p><P>PROBLEM TO BE SOLVED: To achieve power saving as a system without deteriorating access efficiency of respective memory devices. <P>SOLUTION: The memory control circuit includes a command queue holding a plurality of memory access commands, and a plurality of chip selects controlling a plurality of memory devices. The memory control circuit includes a power saving control means shifting the memory devices to a power saving mode for each chip select. When an access command to a memory device as a target is input to the command queue, the power saving control means starts a process to recover the memory device from the power saving mode. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
