Abstract: A method is described. The method includes receiving notice of a page fault. A page targeted by a memory access instruction that resulted in the page fault residing in persistent memory without system memory status. In response to the page fault, updating page table information to include a translation that points to the page in persistent memory such that the page changes to system memory status without moving the page and system memory expands to include the page in persistent memory.
