摘要： A semiconductor memory device includes a sub word line driver for selectively connecting one of sub word lines with a main word line and applying a boosted voltage having a level higher than a power source voltage to a selected sub word line. The device includes a sub word line driver control signal generator. The sub word line driver control signal generator receives an isolation signal applied to electrically insulate a sense amplifier from a bit line connected to memory cells constituting a memory cell array of the device, and generates a driver control signal for determining whether the sub word line driver operates or not. Thereby, a load of sub word line driver control signal generator can be reduced and so power consumption is reduced.

The driver pair may include a pull-up driver and a pull-down driver. One driver may be active when an input signal has a first transition, but not a second transition. The other driver may be active when the input signal has the second transition, but not the first transition. Alternatively, one driver may be inactive when the input signal has the second transition and active for a first portion of the first transition and inactive for a second portion of the first transition. Alternatively, only one driver may be active at any given time.
