摘要:
A method for erasing a flash EEPROM. The flash EEROM includes a number of memory units. First, the flash EEPROM is pre-programmed. Second, the step of erasing the flash EEPROM is performed and the flash EEPROM is then soft-programmed. Subsequently, the final step is performed to determine if the erasing step succeeds.
