<P>PROBLEM TO BE SOLVED: To reduce the power consumption by making off the supply of voltage to the terminal part of a memory bus line in the state where exchange of data is not carried out between a memory controller and a memory device. <P>SOLUTION: A CPU 10 outputs a power saving mode transfer signal. A DC/DC controller 12 makes off the supply of voltage to the terminal 16 of the memory bus line 14 when an access to the memory device 30 is not detected when the power saving mode transfer signal is inputted. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
