US Patent 11977479 Log file system (LFS) invalidation command and operational mode

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.
