VPP power supply having a regulator circuit for controlling a regulated positive potential
 A positive power supply for generating and supplying a regulated positive potential to control gates of selected memory cells via word lines in an array of flash EEPROM memory cells during programming includes a clock circuit (18b) for generating a pair of non-overlapping clock signals and charge pump means (18c) responsive to an external power supply potential (VCC) and to the non-overlapping clock signals for generating a high positive voltage. A regulator circuit (20) responsive to the high positive voltage and a reference voltage is provided for controlling the regulated positive potential so that it is independent of the external power supply potential (VCC).
