Abstract:
Aspects of the present disclosure provide systems and methods for operating a solid state drive (SSD) using two-level indirection architecture. The SSD receives a command to perform a data operation in a NAND array and a logical address for the data operation. The SSD then converts the logical address to a physical address using a two-stage logical-to-physical (L2P) mapping table that includes a first stage stored in a byte-rewritable memory and a second stage stored in a block-erasable non-volatile memory (NVM). The SSD performs the data operation in the NAND array based on the physical address. The byte-rewritable memory may any byte-rewritable persistent memory. The block-erasable low latency NVM may be a flash memory that has lower latency than NAND array.

Claim (Index 22):
The SSD of  claim 16 , wherein:\n the partition table comprises a plurality of partition indexes, wherein each partition index indicates a location of a corresponding one of the L2P table partitions in the block-erasable NVM.
