Radian Memory Systems Assigned Patent

Radian Memory Systems, Inc., Manhattan Beach, CA, has been assigned a patent (11868247) developed by Kuzmin, Andrey V., Moscow, Russia, and Wayda, James G., Laguna Niguel, CA, for a “storage system with multiplane segments and cooperative flash management.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “This disclosure provides for improvements in managing multi-drive, multi-die or multi-plane NAND flash memory. In one embodiment, the host directly assigns physical addresses and performs logical-to-physical address translation in a manner that reduces or eliminates the need for a memory controller to handle these functions, and initiates functions such as wear leveling in a manner that avoids competition with host data accesses. A memory controller optionally educates the host on array composition, capabilities and addressing restrictions. Host software can therefore interleave write and read requests across dies in a manner unencumbered by memory controller address translation. For multi-plane designs, the host writes related data in a manner consistent with multi-plane device addressing limitations. The host is therefore able to “plan ahead” in a manner supporting host issuance of true multi-plane read commands.”

The patent application was filed on 2023-03-21 (18/124514).
