  • Methods and apparatus for implementing a logical to physical address mapping in a solid state drive
    Patent number: 10572391
    Abstract: Aspects of the disclosure provide for managing a logical to physical (L2P) table in a Solid State Drive (SSD). Methods and apparatus provide for using a non-volatile memory (NVM) to store the L2P table in its entirety, where the L2P table is separated into a plurality of partitions. The SSD is partitioned into front and back-end processing portions where a partition table is managed by the back-end portion and includes one or more addresses of partitioned portions of the plurality partitions of the L2P table stored in the NVM. The back-end processing portion receives requests from the host via the front-end processing portion and accesses the partition table for scheduling read or write access to the NVM by determining one or more addresses of the respective partitioned portions of the plurality partitions of the L2P table stored in the NVM from the partition table.
