Abstract
A circuit usable as a word line driver includes a driver that switches in response to a voltage on a control node, and a circuit supplying a voltage to the control node. The circuit that applies a voltage to control node provides a first static current tending to pull the control node up to a first source voltage, and provides a fighting current pulse in response to a signal selecting the driver to pull the control node down to a second source voltage, overcoming the first static current. In addition, a circuit provides a pull-up boost current on a transition of the signal selecting the driver that turns off the fighting current, and applies a boosting current pulse to the control node to assist pulling the control node quickly to the first source voltage.
