Abstract

A memory driver includes a word line driver circuit, a reference circuit, and a bias circuit. The word line driver circuit is coupled to a word line and configured to selectively provide a reference voltage from a reference node to the word line according to an input signal. The reference circuit has a capacitor coupled to the reference node. The reference circuit is configured to store the reference voltage on the capacitor and lower the reference voltage from a first voltage level to a second voltage level when the reference voltage is provided by the word line driver circuit from the reference node to the word line. The bias circuit coupled to the reference node and configured to regulate the reference voltage at the reference node by the second voltage level.
