  • Window based mapping
    Patent number: 10459635
    Abstract: Window based mapping is used to reduce the usage of volatile memory for storing the mapping of logical to physical addresses for accesses to data in a flash drive. Two separate mapping tables for translation of logical addresses to physical addresses (L2P), e.g., an L2P front map and an L2P back map, are used where the L2P front map acts as a window to the L2P back map. The L2P front map has smaller granularity for data accesses than the L2P back map. The data accessed using the L2P front map can allow the flash drive to function with relatively same performance as a fully mapped drive with a single mapping table.
