An apparatus for switching a voltage comprising:
- a plurality of high voltage switching circuits operable in response to a single control signal, and suitable for pumping a voltage level of a switching signal to a target level based on the voltage level of the switching signal;
- and
- a common control unit suitable for generating the single control signal,
- wherein each of the plurality of high voltage switching circuits includes:
- a discharge unit suitable for discharging the voltage level of the switching signal in response to a select signal;
- and
- a high voltage transfer unit suitable for pumping the voltage level of the switching signal, and outputting the pumped voltage level of the switching signal in response to the single control signal.
