Abstract

The present invention provides a voltage generating circuit and a semiconductor memory device having the same. The voltage generating circuit includes an internal voltage generating portion for generating an internal voltage in response to a signal input from an external portion; a sensing portion for outputting a sensing signal when the signal input from the external portion is input again within a predetermined time period; a control signal generating portion for outputting a control signal in response to the sensing signal; and a compensating portion for compensating the internal voltage in response to the control signal.
