A memory management and protection system that manages memory access requests from a number of requestors. Memory accesses are allowed or disallowed based on the permissions assigned to the request based on the memory segment being accessed. The decision to allow or disallow access is made by the extended memory controller by merging the permissions assigned to the memory segment being accessed, and the permissions assigned to the access request by the originating memory controller or other endpoint. |
