Abstract
A word line voltage supply circuit for a nonvolatile semiconductor memory device reduces power supply noise by deactivating a high voltage generator during a verify sensing operation. The word line voltage supply circuit includes a high voltage generator that produces a high voltage signal in response to a control signal from a controller. A voltage regulator regulates the high voltage signal to generate a verify voltage signal that is applied to a selected memory cell. The controller deactivates the control signal during a verify sensing operation so as to eliminate power supply noise caused by the pumping operation of the high voltage generator.
