Title: Body bias using scan chains

Abstract: A logic unit and method incorporating body biasing using scan chains, the logic unit comprising a functional unit block including a body and a scan chain, and a variable voltage source coupled to the scan chain to receive control signals from the scan chain and coupled to the body to provide a bias voltage to the body, and the method comprising identifying a preferred body bias voltage for a functional unit block having a body; and permanently programming a plurality of control signals coupled to a variable voltage source that provides the preferred body bias voltage to the body.
