1. A non-volatile memory device comprising:
- an array of non-volatile memory cells arranged in rows, each row of memory cells coupled to a respective word line;
a voltage selection circuit operable to selectively supply one of at least two voltages to an output node depending upon the nature of an operation being performed by the non-volatile memory device; and
a plurality of word line control circuits coupled to the output node of the voltage selection circuit, each of the word line control circuits coupled to a respective word line in the array of non-volatile memory cells and being operable to selectively couple the voltage supplied to the output node to the respective word line.

Abstract
A word line driver system that utilizes a voltage selection circuit to supply one of several voltages to an output node coupled to a plurality of word line control circuits. Each word line control circuit is coupled to a respective word line in an array of non-volatile memory cells. The voltage selection circuit may include selectable low pass filters for filtering the supplied voltage supplied to the word lines in the array of memory cells without significantly increasing the overall die-size of the device.
