Abstract

An inter-hamming difference analyzer for a memory array having a plurality of sections is provided. The inter-hamming difference analyzer includes a controller, a storage device and a comparator. The controller is configured to obtain contents of the plurality of sections operating in a first operating condition and a second operating condition. The storage device is configured to store the contents of the plurality of sections corresponding to the first operating condition. The comparator is configured to obtain a plurality of inter-hamming differences of the plurality of sections according to the number of unlike bits between the content of a first section of the plurality of sections corresponding to the second operating condition and the contents of a plurality of sections other than the first section stored in the storage device.
