Abstract
A processor semiconductor chip is described. The processor semiconductor chip includes at least one processing core. The processor semiconductor chip also includes a memory controller. The processor semiconductor chip also includes an embedded non flash non-volatile random access memory having a stack of storage cells disposed above the processor semiconductor chip's semiconductor substrate. The embedded non-volatile random access memory is to store boot up program code that, when executed by the processor semiconductor chip, is to analyze a subsequent module of program code so that a maliciously modified version of the subsequent module of program code can be identified. The embedded non-volatile random access memory to also store the subsequent module of program code.
