Abstract
A device is disclosed that includes a memory array, a comparing circuit, and a calculating circuit. The memory array is configured to store a first response of an under-test device. The comparing circuit is configured to compare the first response with a plurality of responses of the under-test device operated in conditions that are different from each other to generate comparing results. The calculating circuit is configured to output a maximum hamming distance between two of the first response and the plurality of responses according to the comparing results.
