ABSTRACT:
In a memory comprising an upper word line and a lower word line for selecting memory cells connected therebetween, a delay circuit connected to the upper word line provides a first signal having a predetermined level when a voltage applied to the upper word line is between a selection voltage and a predetermined voltage, and a second signal, which is a delayed signal of the upper word line voltage signal, when the upper word line voltage changes from the predetermined voltage toward the non-selection voltage. The output of the delay circuit is used to control a switch circuit for discharging the lower word line therethrough.
