ABSTRACT:
Provided is a pass gate circuit capable of operating stably in a transition phase of an input signal, a self-refresh circuit including the pass gate circuit, and a method of controlling the pass gate circuit. The pass gate circuit according to the present invention includes a pass gate unit and a pass gate control unit. The pass gate unit delays an input signal for a fixed duration and outputs the delayed input signal as an output signal in response to a switching control signal. The pass gate control unit outputs the switching control signal, and in response to an internal control signal, determines the existence of a transition in the input signal, and enables or disables the switching control signal according to the determination. The pass gate circuit, the self-refresh circuit including the same, and the control method of the pass gate circuit are capable of operating stably in the transition phase of the input signal.
