Abstract:
An apparatus for generating a pulse which generates an internal signal. The apparatus includes a latch circuit latching an input signal to output a first signal. A clock period detector detects a period of an external clock signal to output a period detecting signal and a delay controller adjusts a delay time of the first signal to output a second signal in response to the period detecting signal. A signal generator receives the first signal and the second signal to output a pulse signal.
