ABSTRACT:
A multi-level high voltage generator according to embodiments of the invention is capable of simultaneously generating high voltages of various levels by using one charge pump. The multi-level high voltage generator includes a charge pump unit, a voltage divider unit, and a pump control unit. The charge pump unit raises an input voltage applied at an input terminal to simultaneously output a number of high voltages having different levels. The voltage divider unit divides the voltages from the charge pump unit. The pump control unit operates according to an enable signal and generates pump control signals in response to a reference voltage, a control clock signal, and a divided voltage from the voltage divider unit. The charge pump unit generates the high voltages and is controlled by the pump control signals from the pump control unit.
