In some implementations, a first lookup table in non-volatile memory maps logical sectors directly into physical pages.

An index cache tree in volatile memory holds the physical addresses of the most recently written or accessed logical sectors in a compressed format."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Index cache tree","description":"Memory mapping techniques for non-volatile memory are disclosed where logical sectors are mapped into physical pages using data structures in volatile and non-volatile memory.
