Abstract
To include an internal voltage generating circuit that includes a capacitor having a first electrode and a second electrode and generates an internal voltage by repeating a charge operation for charging the capacitor to a VDD level and a discharge operation for applying the VDD level to the first electrode of the capacitor to generate a voltage of two times the VDD level on the second electrode, and a control circuit that performs a control to apply a voltage that is lower than the VDD level to the capacitor when the internal voltage generating circuit is in a standby state. According to the present invention, when the internal voltage generating circuit is in a standby state, because a voltage applied to both ends of the capacitor is reduced, it is possible to reduce the power consumption due to a leakage current.
