Abstract: A method of writing to a tiered memory system of a computing device, the tiered memory system including volatile memory and persistent memory (PMEM), includes the steps of: in response to a first write request including first data to write to a first page of the tiered memory system, copying contents of the first page to a second page located in the PMEM; after copying the contents of the first page to the second page, writing the first data to the second page; and after writing the first data to the second page, updating a first mapping of the tiered memory system to reference the second page instead of the first page.
