ABSTRACT:
A flash memory device including a memory cell array block including a plurality of flash memory cells. A program verify voltage generating unit variably generates a program verify voltage that verifies flash memory cells programming. A wordline level selecting unit transfers the program verify voltage to the flash memory cells. And a page buffer, including a latch, stores flash memory cell data and resets the latch whenever the program verify voltage is lowered.
