The negative voltage generating device includes a current interrupting controller, a voltage generating controller, and a negative voltage generator. The current interrupting controller outputs a current interrupting control signal in response to a control signal, which is enabled during the application of a power-up signal. The voltage generating controller compares a first reference voltage to a feedback voltage in response to the current interrupting control signal and outputs a voltage generating control signal. The negative voltage generator generates the feedback voltage and a second negative voltage by receiving the first negative voltage in response to the voltage generating control signal.
