A data strobe signal generating circuit includes a pre-driver control unit for selectively transferring a ground voltage and a supply voltage, as a first control signal and a second control signal, in response to first and second clock pulse signals, wherein the second control signal is driven in response to a preamble signal, a pre-driver for generating a driving signal in response to the first and second control signals and the preamble signal, and an output buffer for driving an output pad in response to the driving signal.
