Abstract
A nonvolatile semiconductor memory apparatus includes a control unit configured to generate a select signal and a driving control signal in response to a first enable signal and a second enable signal; a level shifting unit configured to enable a first shifting signal or a second shifting signal to a level of a pumping voltage in response to the select signal and the driving control signal; a first switching unit configured to apply a program voltage to a word line when the first shifting signal is enabled to the level of the pumping voltage; and a second switching unit configured to apply a pass voltage to the word line when the second shifting signal is enabled to the level of the pumping voltage.
