Abstract
An integrated circuit has a first component that has a dynamic characteristic that varies among like integrated circuits, for example, among integrated circuits fabricated using the same lithography mask. Operating the first component produces an output that is dependent on the dynamic characteristic of the first component. A digital value associated with the integrated circuit is generated using the output of the first component, and then the generated digital value is used in operation of the integrated circuit.
