ABSTRACT:
An integrated circuit has a built-in EEPROM which utilizes a high voltage to write or erase data. The integrated circuit operates with a lower power supply voltage. Switches supply a high voltage to bit lines, control gate lines, and word lines. Each switch includes a multi-stage charge pump comprising diode-connected transistors and capacitors. The switch has an enhanced charge capability and can transfer a high voltage from a low power supply voltage. Thus, the switch can operate successfully with a low power supply voltage.
