  • Patent number: 9323688
    Abstract: A data access system including a storage device and a processor, which includes one or more levels of cache (LOC). In response to data required by the processor not being within the LOC, the processor generates a physical address to be accessed within the storage device in order to retrieve the data. The storage device includes a main memory and a cache module, which is configured as a final level of cache (FLOC) to be accessed by the processor prior to accessing the main memory. The cache module includes a controller that, in response to the data not being cached within the LOC, converts the physical address into a virtual address within the FLOC. The FLOC uses the virtual address to determine whether the data is within the FLOC. If the data is not within the FLOC, the cache module or the processor retrieves the data from the main memory.
