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.

Claim (Index 32):
A method for operating a solid state drive (SSD) including a non-volatile memory (NVM), the method comprising:\n receiving a host request at a front-end portion; initiating signaling to a back-end portion for reading a logical to physical address table (L2P table) stored entirely in a non-volatile memory (NVM) communicatively coupled to the back-end portion, wherein the L2P table includes a plurality of L2P table partitions; determining an L2P table partition to be read from the NVM based on reading a partition table stored in a random access memory (RAM) coupled to the back-end portion, the partition table including a plurality of partition addresses corresponding to the plurality of L2P table partitions stored in NVM to determine a partition address of a desired L2P table partition; reading the desired L2P table partition from the NVM into the RAM based on the partition address of the desired L2P table partition; and performing the host request using at least the back-end portion based on a physical NVM address determined from the desired L2P table partition.
