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 mappings are sufficient to map all pages within the coalesced region. Accordingly, a memory subsystem can cache a single coalesced mapping and not all of them. The single cached coalesced mapping may be used to translate all of the virtual addresses to physical addresses for the corresponding contiguous memory space.
