In an embodiment, memory access requests for information stored within a system memory pass through an integrated circuit. The system memory may include a micro-architectural memory region to store instructions and/or data, where the micro-architectural memory region is to be exclusively accessible by a micro-architectural agent The integrated circuit may include memory access director to direct memory access requests to the micro-architectural memory region if the memory access director determines that the memory access request includes a location within the at least one micro-architectural memory region and the micro-architectural agent is operating in a micro-architectural memory region access mode.
