Abstract

An EEPROM utilizing a tunneling electron for writing and/or erasing, has charge pump circuits for pumping charge onto selected column and row lines up to a high voltage. In each of the charge pump circuits, a transistor is provided for intercepting clock pulses applied to a capacitor in each of the charge pump circuits connected to unselected column and row lines.
