Abstract
In one embodiment of the invention, an update circuit having a bus driver to drive a bus dynamically receives an update compensation code. The bus driver receives data at a data clock signal. The update compensation code controls impedance matching at the bus driver according to the data. A code generator generates the update compensation code at a base clock signal. The base clock signal is synchronized with the data clock signal. The base clock signal has an update interval and a quiet interval. A distribution ring interface distributes the update compensation code to the update circuit synchronously with the base clock signal.
