STORING TRANSLATION LAYER METADATA IN HOST MEMORY BUFFER

Abstract:

An example method of storing translation layer metadata in a host memory buffer comprises: retrieving, from the first memory device, translation layer metadata comprising one or more logical-to-physical (L2P) records, wherein an L2P record of the one or more of L2P records maps a logical block address to a physical address identifying a memory block in the memory system; generating protection metadata for at least a portion of the translation layer metadata; and causing a host system connected to the memory system to store the portion of the translation layer metadata and the protection metadata in a host memory buffer residing on a second memory device of the host system.
