Title: BLOCK STORAGE APERTURES TO PERSISTENT MEMORY
Abstract:
Apparatus and methods for accessing a non-volatile memory (NVM) device in a computer system that includes at least one host processor and at least one memory bus. The NVM device is communicably coupleable to the memory bus through an NVM device controller, thereby allowing the host processor to access persistent data storable within the NVM device by issuing one or more memory load/store commands to the NVM device controller over the memory bus. Because the NVM device controller includes at least one block window or aperture that defines at least one address range for accessing the persistent data storable within the NVM device, the computer system can exploit the full capacity of the NVM device without being unduly constrained by physical addressing limits imposed by the host processor, or by limits imposed by an operating system executed by the host processor.
