Abstract
The invention is an internal power voltage generating circuit, adjusted such that an internal power voltage becomes the reference voltage. The internal power voltage generating circuit further includes: a charge share circuit, including a charging capacitor, an initial voltage adjusting circuit and a charge reset circuit. The charging capacitor is connected to a differential amplifier via a switch circuit, and is charged by charges of a control voltage. The initial voltage adjusting circuit adjusts and applies an initial voltage to the charging capacitor. The charge reset circuit discharges the charging capacitor. When the internal power voltage is lower than a reference voltage, the charging capacitor having the initial voltage is connected to the differential amplifier, and the charges of the control voltage are transferred to the charging capacitor during a transfer period.
