Disclosed is a semiconductor memory device which comprises an internal clock generating circuit receiving a clock signal from outside to generate an internal clock signal to be supplied to a random access memory. The internal clock generating circuit includes a circuit for canceling internal clock generation for generating a signal activating an internal clock signal during operation based on an external clock signal, a chip select signal and a write enable signal, and a circuit for setting the internal clock signal based on an output of the circuit for canceling internal clock generation and for resetting the internal clock signal based on an internal clock reset signal. A dummy cycle is provided next to a write cycle.
