  • Log file system (LFS) invalidation command and operational mode
    Patent number: 11977479
    Abstract: A data storage device includes a memory device and a controller coupled to the memory device. The controller is configured to add one or more entries to a log file system (LFS) invalidation table and scan the LFS invalidation table during a storage optimization operation. Each entry of the one or more entries maps a new valid logical block address (LBA) to an old invalidated LBA. The new valid LBA is updated version of the old invalidated LBA. The storage optimization operation includes moving data from a first location to a second location.

  • Storage system and method for non-blocking coherent re-writes
    Patent number: 11847343
    Abstract: A host sends a storage system a command to read data from a memory and then a command to write the data back to the memory to defragment the data. The host sends flags along with the commands. The flag sent with the read command causes the storage system to take a snapshot of the logical-to-physical address map relevant to the data. The flag sent with the write command causes the storage system to compare the snapshot with the current version of the logical-to-physical address map and write the data back to the memory only if there is a match.
