ABSTRACT:
A decoder for a non-volatile semiconductor memory device includes a level shifter configured to generate a negative first voltage at an output thereof responsive to a first state of a global word line and to generate a second voltage more positive than the first voltage responsive to a second state of the global word line. The decoder further includes a local word line driver having an input coupled to the output of the level shifter and configured to apply a voltage on a partial word line to a local word line when the output of the level shifter is at the first voltage and to apply the first voltage to the local word line when the output of the level shifter is at the second voltage.
