FLASH MEMORY DEVICE AND WORDLINE VOLTAGE GENERATING METHOD THEREOF

摘要

PURPOSE: A flash memory device and a method for generating a word line voltage thereof are provided to efficiently read and verify data distributed in a negative voltage region by continuously generating the negative word line voltage without a word line recovery. CONSTITUTION: A flash memory cell array(110) comprises a plurality of flash memory cells arranged in an intersection between a plurality of word lines and a plurality of bit lines. A voltage generating unit(170) generates a plurality of word line voltages applied to the word lines. A control logic unit(190) controls a voltage generation operation of a voltage generating unit. The voltage generating unit alternatively generates a negative word line voltage and a positive word lines voltage.
