The processor, in response to data required by the processor not being cached within one or more levels of cache of the processor, generates a first physical address (PA). The cache module includes a memory and first and second controllers. The memory is a final level of cache. The first controller converts the first PA into a virtual address. The second controller: converts the virtual address into a second PA; based on the second PA, determines whether the data is cached within the memory; and if the data is cached, accesses and forwards the data to the processor. The first or second controller determines whether a cache miss has occurred and, in response to a cache miss and based on the second PA or a third PA of the storage drive, retrieves the data from the storage drive."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for accessing data stored in a storage system that includes both a final level of cache and a main memory","description":"A data access system including a storage drive, processor and cache module.
