Abstract:
An apparatus includes an error correction component coupled to read recovery control circuitry. The error correction component can be configured to perform one or more initial error correction operations on codewords contained within a managed unit received thereto. The read recovery control circuitry can be configured to receive the error corrected codewords from the error correction component and determine whether codewords among the error corrected codewords contain an uncorrectable error. The read recovery control circuitry can be further configured to determine that a redundant array of independent disks (RAID) codeword included in the plurality of error corrected codewords contains the uncorrectable error, request that codewords among the error corrected codewords that contain the uncorrectable error are rewritten in response to the determination, and cause the plurality of error corrected codewords to be transferred to a host coupleable to the read recovery control circuitry.
