摘要:
A method for decoding data in a data storage system includes generating an output bit stream; generating a first error corrected bit stream in dependence on the output bit stream; generating a second error corrected bit stream in dependence on the first error corrected bit stream; generating a checksum in dependence of the second error corrected bit stream; and, in the event that the checksum is indicative of errors in the second error corrected bit stream and the second error corrected bit stream comprises at least one correct interleave: supplying data indicative of locations of correct bits in the second error corrected bit stream; and, regenerating the first error corrected bit stream in dependence on the pinning data.
