Abstract
A power supply control system for memory systems includes a power control unit for controlling the power supply for read/write operation when data is read into MOS-IC memory chips. The power control unit is constructed in such a manner that necessary power supply voltage for read/write operation is supplied to the selected memory chip during the time period when the read/write operation is executed, while no power is supplied to the non-selected memory chips.
