  • Data management in solid state storage systems
    Patent number: 9037951
    Abstract: Methods and apparatus are provided for controlling data management operations including storage of data in solid state storage of a solid state storage system. Input data is stored in successive groups of data write locations in the solid state storage. Each group comprises a set of write locations in each of a plurality of logical subdivisions of the solid state storage. The input data to be stored in each group is encoded in accordance with first and second linear error correction codes. The encoding is performed by constructing from the input data to be stored in each group a logical array of rows and columns of data symbols. The rows and columns are respectively encoded in accordance with the first and second linear error correction codes to produce an encoded array in which all rows correspond to respective first codewords and columns correspond to respective second codewords.
