Scalable Memory Protection Mechanism

An apparatus to protect contents of a memory region is presented. In one embodiment, the apparatus includes a non-volatile memory, memory check logic to generate check values for protected memory regions, and comparison logic to compare stored check values from the non-volatile memory with generated check values from the memory check logic. The apparatus also includes security logic to prevent executing code in the protected memory regions if the comparison logic detects a mismatch between the stored check values and the generated check values.
