Abstract
Methods, systems, and structures for stress balancing field effect transistors subject to bias temperature instability-caused threshold voltage shifts. A method includes characterizing fatigue of a location in a memory array by skewing a bit line voltage of the location. The method also includes determining that the location is unbalanced based on the characterizing. Further, the method includes inverting a logic state of the location. Additionally, the method includes changing a value of an inversion indicator corresponding to the location.
