Local word line driver and flash memory array device thereof

In a local word line driver of an NOR flash memory and its flash memory array device, the local word line driver is provided for driving a local word line in a sector of a memory array, and the local word line driver has two transistors including a first transistor and a second transistors, and the first and second transistors are NMOS transistors, and thus achieving the effects of reducing the area occupied by circuits on the local word line driver and the die size, and saving the area for the use by memory units.
