USING HYBRID-SOFTWARE/HARDWARE BASED LOGICAL-TO-PHYSICAL ADDRESS MAPPING TO IMPROVE THE DATA WRITE THROUGHPUT OF SOLID-STATE DATA STORAGE DEVICES

摘要

The present disclosure relates to the field of solid-state data storage, and particularly to improving the write throughput performance of solid-state data storage devices. A method for providing logical block address (LBA) to physical block address (PBA) binding in a storage device includes: receiving at least one thread at a hardware engine of the device controller of the storage device, each thread including data and LBAs for the data; writing the data into a write buffer of the storage device; binding, by the hardware engine of the device controller, a sequence of contiguous PBAs for a section of the memory to the LBAs for the data in the write buffer; determining if the write buffer contains enough data for the section of the memory; and if the write buffer contains enough data for the section of the memory, writing the data to the section of the memory.
