Abstract
PURPOSE: To reduce the amount of average power consumption, by supplying the power only when necessary for the reading or writing of the data and at the same time supplying the necessary power only to the chip which performs the reading or writing among several units of the memory chips.
CONSTITUTION: The reading or writing command given from the processor 32 is received via the memory control part 35. In addition to the above action, the memory chips 211 and 212 write the data into the area designated by the address signal sent from the data line 310 and also read the data out of the designated area. The power supply control part 36 supplies the power only to these ships 211 and 212 which perform the reading and writing actions by the data control signals C1 and C2 supplied from the processor 32. Then the address signal is applied to the control part 36 from the memory control part 35, and the power is supplied the memory chip via the power supply line 41 during the writing or reading address. Thus the amount of average power consumption can be reduced.
