  • Patent number: 10176042
    Abstract: Provided are a method, system, and apparatus using reliability information from multiple storage units and a parity storage unit to recover data for a failed one of the storage units. A decoding operation of the codeword is performed in each of the storage units comprising the data storage units other than the target data storage unit and the parity storage unit to produce reliability information. In response to the decoding operation failing for at least one additional failed storage unit comprising the data and/or parity storage units other than the target data storage unit that failed to decode, reliability information is obtained for the data portion of the at least one additional failed storage unit. The reliability information obtained from the storage units other than the target data storage unit is used to produce corrected data for the data unit in the target data storage unit.

  • Patent number: 9411683
    Abstract: Apparatus, systems, and methods for error correction in memory are described. In one embodiment, a memory controller comprises logic to load an error correction codeword retrieved from a memory and apply a first error correction decoder to decode the error correction codeword, wherein the first error correction decoder implements a bit-flipping error correction algorithm which utilizes a variable bit-flipping threshold to determine whether to flip a bit in an error correction codeword. Other embodiments are also disclosed and claimed.
