Abstract: Bit generating cells are subjected to processes that accelerate aging-related characteristics before they are configured for use in the field (enrolled). Aging improves the reliability of the cells by shifting device characteristic in a direction that improves the cell behavior with respect not only to aging but also environment variations. Outputs of the cells are read, and the cells are reconfigured with a bias to output an opposite value, and then aged for enrollment.
