HyperStone Assigned Patent
ECC based on high-rate Generalized Concatenated Codes
By Francis Pelletier | October 30, 2020 at 2:05 pmHyperStone GmbH, Constance, Germany, has been assigned a patent (10,790,855) developed by Freudenberger, Juergen, Radolfzell, Germany, Spinner, Jens, Constance, Germany, and Baumhof, Christoph, Radolfzell, Germany, for “method and device for error correction coding based on high-rate Generalized Concatenated Codes.“
The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Field error correction coding is particularly suitable for applications in non-volatile flash memories. We describe a method for error correction encoding of data to be stored in a memory device, a corresponding method for decoding a codeword matrix resulting from the encoding method, a coding device, and a computer program for performing the methods on the coding device, using a new construction for high-rate generalized concatenated (GC) codes. The codes, which are well suited for error correction in flash memories for high reliability data storage, are constructed from inner nested binary Bose-Chaudhuri-Hocquenghem (BCH) codes and outer codes, preferably Reed-Solomon, RS) codes. For the inner codes extended BCH codes are used, where only single parity-check codes are applied in the first level of the GC code. This enables high-rate codes.”
The patent application was filed on April 25, 2019 (16/395,046).
