Abstract
A host device includes system memory that includes a logical-to-physical (L2P) cache and a second cache. The host device also includes a host controller interface (HCI) configured to be coupled to a flash memory device. The HCI is configured to determine that a particular region of a L2P address mapping table is to be removed from the L2P cache. The L2P address mapping table is configured to include mappings between logical memory addresses and physical memory addresses of the flash memory device. The HCI is also configured to identify a particular sub-region of the particular region having an access metric that satisfies a retention criterion. The HCI is further configured to store the particular sub-region into the second cache. The HCI is also configured to remove the particular region from the L2P cache.
