In accordance with embodiments of the present disclosure, a method may include generating a random number to be associated with an information handling resource. More specifically, but not exclusively, the invention is concerned with interconversion between cortisone and cortisol in humans. The second AP pinned layer of each of the first and second AP pinned layer structures is composed of a material which causes each AP pinned layer structure to be self-pinned. Thus, with the same configuration irrespective of data bit width, compression of data bits in the multi-bit test can be performed to output the compression result to the same data terminal.
