A memory management unit (MMU) receives a request to translate a virtual memory address to a physical memory address and searching a translation lookaside buffer (TLB) for a translation to the physical memory address based on the virtual memory address. If the translation is not found in the TLB, the MMU searches an external memory translation lookaside buffer (EMTLB) for the physical memory address and performs a page table walk, using a page table walker (PTW), to retrieve the translation. If the translation is found in the EMTLB, the MMU aborts the page table walk and returns the physical memory address. If the translation is not found in the TLB and not found in the EMTLB, the MMU returns the physical memory address based on the page table walk."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"External memory based translation lookaside buffer","description":"Methods, devices, and systems for virtual address translation.
