Patent ID: 11537530

Abstract:
Systems, apparatus and methods are provided for logical-to-physical (L2P) address translation. A method may comprise receiving a request for a first logical data address (LDA), and calculating a first translation data unit (TDU) index for a first TDU. The first TDU may contain a L2P entry for the first LDA. The method may further comprise searching a cache of lookup directory entries of recently accessed TDUs using the first TDU index, determining that there is a cache miss, generating and storing an outstanding request for the lookup directory entry for the first TDU in a miss buffer, retrieving the lookup directory entry for the first TDU from an in-memory lookup directory, determining that the lookup directory entry for the first TDU is not valid, reserve a TDU space for the first TDU in a memory and generating a load request for the first TDU.
