Abstract
A semiconductor memory device having a plurality of memory array banks, a plurality of active array voltage generators, a standby array voltage generator and a plurality of switching means is provided. The semiconductor memory device includes a plurality of memory array banks in which information is stored, a plurality of active array voltage generators connected to the memory array banks, for generating predetermined active voltages in response to memory array bank enable signals for activating the memory array banks, a standby array voltage generator for generating a predetermined standby voltage so that the memory array banks are maintained in a standby state for operation, and a plurality of switching means connected between the memory array banks and the standby array voltage generator, for disconnecting the output of the standby array voltage generator from memory array banks in response to memory array bank enable signals for activating the memory array banks. The power consumption of the semiconductor memory device is reduced.
