Abstract
An integrated semiconductor circuit has a boost circuit that may improve boost operation speed. The boost circuit employs a P-channel type transistor as a driver. The back gate of the P-channel type transistor is connected to a charge-up circuit so that the back gate may be charged to a predetermined level before a boost signal is applied to the driver.
