Abstract
The present invention provides a method and apparatus is provided for calibrating a driver impedance in an integrated circuit device. The method includes providing a signal from a synchronous circuit that is indicative of an impedance mismatch between a driver circuit and a load. The method also includes selecting one of a plurality of impedances of the driver circuit to reduce the impedance mismatch in response to the signal.
