ABSTRACT:
A flash memory device applies a low read voltage at increased flash memory device temperatures. A high read voltage is applied when a supply voltage is high, thereby maintaining a stable threshold voltage margin of a programmed cell or an erased cell. As a result, the reliability of the flash memory cell is enhanced.
