1. A high voltage generator comprising:
- a voltage converting device configured to output an output voltage having a level higher than a level of an input voltage; and
a precharge controller configured to increase the level of the input voltage of the voltage converting device up to a level of an external voltage while preventing breakdown of a circuit in the voltage converting device receiving the input voltage based on a reference voltage and the output voltage of the voltage converting device,wherein the precharge controller comprises a voltage transmitting device configured to transmit the external voltage to an input node of the voltage converting device in response to a control signal.

Abstract
A high voltage generator includes a voltage converting device configured to increase a level of an input voltage and output an output voltage having a level higher than the level of the input voltage. The high voltage generator also includes a precharge controller configured to gradually increase the level of the input voltage up to a level of an external voltage based on a reference voltage and the output voltage.
