Abstract
A flash EEPROM having an array of memory cells which include a common source line connecting together source electrodes of the memory cells. A resistive feedback element is coupled in series between the common source line and a positive potential when the memory cells must be electrically erased. The Flash EEPROM includes a voltage limiting circuit coupled to the common source line for limiting the potential of the common source line to be prescribed maximum value lower than the positive potential.
