PURPOSE: A pulse switch circuit for a semiconductor memory device is provided to secure sufficient switching time to stabilize a circuit operation by processing output signal with feed-back process to minimize effect of loading value of an output terminal and removing large time delayed circuit. CONSTITUTION: A pulse switch circuit for a semiconductor memory device comprises a first/second logic unit connected between an input terminal and a first/second output terminal, an inverter unit(26) for inverting the output signal of the first logic unit so as to input the inverted signal to the second logic unit, and a delay unit for delaying output signal of the second logic unit to input the delayed signal to the first logic unit. The output signal of the first/second logic unit is delayed for some time and is outputted according to enable signal, input pulse, inverted enable signal and pumping voltage.
