Abstract:
A method of accessing memory, in accordance with one embodiment, includes receiving a memory access request that includes a virtual address. An address of a given page table is determined utilizing a page directory stored in a particular one of a plurality of computing device-readable media. A given one of the plurality of computing device-readable media that stores the given page table is determined from a table aperture attribute in the page directory. A given physical address of a page is determined utilizing the given page table stored in the given computing device-readable media. A corresponding one of the plurality of computing device-readable media that stores the page is determined from a page aperture attribute in the given page table. The corresponding computing device-readable media at the given physical address is then accessed.
