Abstract
A multi-bank semiconductor memory device includes a multi-bank memory; a voltage generator having one standby driving circuit and a plurality of active driving circuits and supplying a power source voltage required for a semiconductor device; and, an up/down counter for counting a low access signal and a low precharge signal and outputting a multi-bit driving enable signal for driving the plurality of active driving circuits differentially in performing an interleaving operation. When a plurality of banks are accessed, the number of banks being currently accessed is counted by using the low access signal and the low precharge signal. The number of the voltage driving circuits is increased and decreased according to the count value.
