Abstract:
A nonvolatile memory controller may recover encoded data using the outer error correction code of the encoded data if it is determined that a correction capacity of the outer error correction code is not exceeded. Alternatively, the nonvolatile memory controller may recover the encoded data using the inner error correction code of the encoded data followed by the outer error correction code of the encoded data if it is determined that the correction capacity of the outer error correction code is exceeded. Additionally, if it is determined that the correction capacity of the outer error correction code is exceed after recovering the data using the inner error correction code, the nonvolatile memory storage module may perform a redundant array of independent disks (RAID) operation to recover the data.
