Abstract:
A method and a storage system are provided for implementing host logical address to physical memory address mapping for persistent storage media including flash memory. Numerical compositions at multiple levels of granularity are used to store the logical address to physical memory address mappings. A plurality of groupings, each grouping including a fixed number of blocks is encoded using recursive composition, eliminating the need to store separate lengths.
