A flash memory integrated circuit includes a plurality of flash memory arrays. A global word line driver is associated with each array, each global word line driver coupled to a plurality of select lines. A plurality of sense amplifiers are individually coupled to a plurality of bit lines. A plurality of sub arrays in each array each include a plurality of NAND flash memory cells coupled to local word lines and local bit lines. A local word line driver is associated with each sub-array and coupled to the plurality of select lines and configured to drive ones of the local word lines in its sub array associated with selected ones of the plurality of NAND flash memory cells in its sub-array. A local bit line driver is coupled between selected ones of the local bit lines in each sub array and selected ones of the plurality of bit lines.
