Abstract
A high voltage switch of a nonvolatile memory device includes a depletion type NMOS transistor configured to switch a second driving voltage in response to an output signal of the high voltage switch; at least one inverter configured to convert a voltage of an input signal of the high voltage switch into a first driving voltage or a ground voltage, wherein the first and second driving voltages are received from an external device; and a PMOS transistor configured to transfer the second driving voltage provided to a first terminal of the PMOS transistor from the depletion type NMOS transistor to a second terminal of the PMOS transistor as the output signal in response to an output of the at least one inverter, wherein the output of the at least one inverter is transferred to a gate terminal of the PMOS transistor.
