ABSTRACT:
An input buffer includes a driving signal generation unit, a comparison signal generation unit, and a driving unit. The driving signal generation unit is configured to generate first and second driving signals which are selectively enabled in response to a control signal generated depending on a level of an input signal. The comparison signal generation unit is configured to compare the level of the input signal with the level of a reference voltage and generate a comparison signal. The driving unit is configured to buffer the comparison signal and drive an output signal with a drivability determined by the first and second driving signals.
