Abstract:
A method of accessing a persistent memory over a memory interface is disclosed. In one embodiment, the method includes allocating a virtual address range comprising virtual memory pages to be associated with physical pages of a memory buffer and marking each page table entry associated with the virtual address range as not having a corresponding one of the physical pages of the memory buffer. The method further includes generating a page fault when one or more of the virtual memory pages within the virtual address range is accessed and mapping page table entries of the virtual memory pages to the physical pages of the memory buffer. The method further includes transferring data between a physical page of the persistent memory and one of the physical pages of the memory buffer mapped to a corresponding one of the virtual memory pages.

Claim (Index 1):
A method of accessing a DIMM-attached storage subsystem over a DIMM interface configured to be communicatively coupled to a memory buffer, a DIMM controller, and the DIMM-attached storage subsystem, comprising:\n generating a page fault when a virtual address within a virtual memory address space that is not mapped to a corresponding physical address within a physical memory address space of the memory buffer is accessed; in response to the page fault,\n mapping the virtual address within the virtual memory address space to a physical address within the physical memory address space of the memory buffer; and \n queuing one or more commands in a command buffer of the DIMM controller to write existing data in the mapped physical address within the physical memory address space of the memory buffer to the DIMM-attached storage subsystem and erase the existing data in the mapped physical memory address within the physical memory address space of the memory buffer.
