ABSTRACT:
A word line driver includes multiple current paths for driving a word line of a memory device to a negative voltage and a positive voltage. When driving the word line from the negative voltage to the positive voltage, the word line driver uses a first current path to drive the word line to the positive voltage in one stage. When driving the word line from the positive voltage to the negative voltage, the word line driver drives the word line from the positive voltage to ground using the first current path in a first stage. In a second stage, the word driver further drives the word line from ground to the negative voltage in using a second current path.
