Radian Memory Systems LLC (Radian) has filed a patent infringement lawsuit against Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. in the Eastern District of Texas in December 2024.
The litigation centers on alleged violations of seven patents owned by Radian, which focus on non-volatile memory (NVM) storage and flash memory management technologies.
The patents at issue are:
U.S. Patent No. 11,544,183: Nonvolatile memory controller host-issued address delimited erasure and memory controller remapping of host-address space for bad blocks.
U.S. Patent No. 11,709,772: Storage system with multiplane segments and cooperative flash management.
U.S. Patent No. 11,681,614: Storage device with subdivisions, subdivision query, and write operations.
U.S. Patent No. 11,740,801: Cooperative flash management of storage device subdivisions.
U.S. Patent No. 11,347,657: Addressing techniques for write and erase operations in a non-volatile storage device.
U.S. Patent No. 11,347,656: Storage drive with geometry emulation based on division addressing and decoupled bad block management.
U.S. Patent No. 11,307,995: Storage device with geometry emulation based on division programming and decoupled NAND maintenance.
The contested patents cover advancements in flash memory technology, including NAND flash management and architecture, and non-volatile memory storage systems emphasizing controllers, data reliability, and wear leveling. They also involve innovative approaches to storage device operations, such as geometry emulation, advanced addressing techniques, and decoupled maintenance processes for NAND flash.
