Abstract
A method for correcting of asymmetric shifts in threshold voltage of transistors caused by effects such as negative-bias temperature instability (NBTI) during burn-in. The method may include providing logic patterns to an integrated circuit, such that devices that were stressed during burn-in are relaxed, and devices that suffered less stress during burn-in are stressed.
