  • Current-regulated, voltage-regulated erase circuit for EEPROM memory
    Patent number: 4888738
    Abstract: A control circuit for erasing EEPROM memory cells is disclosed, including a charge pump having two switched constant current sources driven by opposing clocks. Current produced by the current sources is coupled to a node from where it is used to erase EEPROM memory cells. A switch is provided to isolate the device being erased by floating its source.
