A Flash EEPROM includes a negative voltage generator for generating a negative voltage to be supplied to control gate electrodes of memory cells for erasing the memory cells. The Flash EEPROM also has a first positive voltage generator for generating a first positive voltage, independent from an external power supply of the Flash EEPROM, to be supplied to source regions of the memory cells during erasing.
