Abstract
Embodiments of memory devices, computer systems, security apparatus, data handling systems, and the like, and associated methods facilitate security in a system incorporating the concept of a security perimeter which combines cryptographic and physical security. The memory device can comprise a memory operable to store information communicated with a processor, and a logic operable to create at least one cryptographic security perimeter enclosing at least one selected region of the memory and operable to manage information communication between the processor and the at least one selected region of the memory.
