A one-shot circuit comprises a pulse generation circuit having an external clock terminal adapted to receive an external clock signal, a reset terminal coupled to receive a reset signal, and an internal clock terminal on which the pulse generation circuit develops an internal clock signal. The pulse generation circuit operates in a first mode to drive the internal clock signal from a first level to a second level in response to a transition of the external clock signal from a first level to a second level. The pulse generation circuit operates in a second mode to drive the internal clock signal from the second level to the first level in response to the reset signal going active. A delay circuit has input and output terminals coupled to the internal clock terminal and reset terminal, respectively, of the pulse generation circuit. The delay circuit operates to drive the reset signal active a delay time after the pulse generation circuit drives the internal clock signal from the first level to the second level. The delay circuit further operates, while maintaining the reset signal active, to precharge in response to the reset signal going active.
