Abstract
A voltage switching circuit includes: a control signal generation block configured to include a high voltage switching block which controls an electric current flowing according to a high voltage in response to a voltage level of a low voltage control signal and generates complementary high voltage control signals; and a high voltage transfer block configured to be driven according to the complementary high voltage control signals, and generate a switching signal, the voltage level of which is raised based on the high voltage so that the switching signal has substantially the same level as the high voltage.
