Abstract
Techniques for improved semiconductor inventory tracking, control, and testing are provided. The techniques include marking the semiconductor packaging with a 2-dimensional ('2D') bar code that is stored in a data server. The data server associates the 2D barcode with performance data for the semiconductor, as well as with a 'circuit-based identifier,' which comprises hard-wired electrical features that uniquely identify the semiconductor and that are embedded within the semiconductor. Associating the 2D bar code with chip performance reduces the number of times that a chip needs to be tested. Associating the 2D bar code with the circuit-based identifier provides certain functionality such as anti-counterfeiting functionality, device verification, and the like.
