Abstract
A fast pre-charge circuit and method of providing a fast pre-charge for an integrated circuit memory device is disclosed. The fast pre-charge circuit comprises an address calculating unit and a multi-power driver. The address calculating unit detects the sector distance from driver of the integrated circuit memory device, and the driver provides a voltage to the loading of the integrated circuit memory device based on an output of the address calculating unit. Unlike a conventional fixed-power wordline driver, the driver of the present invention provides multiple voltage levels to the wordline or dynamically adjusts for different loading situations.
