Latest Patents

David holds a patent for "On-SSD-copy techniques using copy-on-write." This invention allows for efficient data copying by tracking indirection updates to the copied data without duplicating it. The method involves receiving a copy command to transfer data from a source logical block address (LBA) to a destination LBA. An entry in a logical-to-physical (L2P) table is updated to refer to the same physical address as the source LBA's entry. Flags in the L2P table are modified to indicate that multiple LBAs refer to the same physical address. A token is stored on the storage device before the actual data copying occurs, allowing for an acknowledgment to be sent to the host, indicating the completion of the copy command. This innovative approach triggers a data copy upon subsequent writes to either the source or destination LBAs.
