Abstract

Dirty Logical-to-Physical (L2P) entries in an L2P indirection table stored in a host volatile memory buffer are flushed to non-volatile memory in the solid state drive through the use of a write-back mode based on flush checkpoints. The use of write-back mode to flush dirty entries in the L2P indirection table to non-volatile memory in the solid state drive based on flush checkpoints results in an increase in the write bandwidth of the solid state drive.
