Abstract
A memory access technique, in accordance with one embodiment of the present invention, includes coalescing mappings between virtual memory and physical memory when a contiguous plurality of virtual pages map to a contiguous plurality of physical pages. Any of the coalesced page table entries are sufficient to map all pages within the coalesced region. Accordingly, a memory subsystem can redirect one or more pending page table entry fetch requests to an appropriate coalesced page table entry.
