Abstract
A semiconductor memory device has a clock input buffer that is turned 'on' or 'off' in response to a first control signal. The clock input buffer is configured to buffer an external clock signal in order to output a buffered clock signal. The memory device further includes an internal clock generator that is configured to generate an internal clock signal in response to the buffered clock signal. The generation of the internal clock signal is started in response to a second control signal.
