Radian Memory Systems Assigned Patent

Techniques for managing writes in NVM

Radian Memory Systems, Inc., Manhattan Beach, CA, has been assigned a patent (11972153) developed by Lercari, Robert, Thousand Oaks, CA, Jadon, Mike, Manhattan Beach, CA, and Kuzmin, Andrey V., Moscow, Russia, for techniques for managing writes in nonvolatile memory.

The abstract of the patent published by the U.S. Patent and Trademark Office states: “This disclosure provides techniques for managing writes of data useful for storage systems that do not permit overwrite of a logical address. One implementation provides a nonvolatile memory storage drive, such as a flash memory drive, that provides support for zoned drive and/or Open Channel-compliant architectures. Circuitry on the storage drive tracks storage location release metadata for addressable memory space, optionally providing to a host system information upon which maintenance decisions or related scheduling can be based. The storage drive can also provide buffering support for accommodating receipt of out-of-order writes and unentanglement and performance of out of order writes, with buffering resources being configurable according to any one of a number of parameters. The disclosed storage drive facilitates reduced error rates and lower request traffic in a manner consistent with newer memory standards that mandate that writes to logical addresses be sequential.

The patent application was filed on 2023-01-13 (18/097024).
