    Abstract: Methods are systems for calculating log-likelihood ratios for a decoder utilized in an electronic non-volatile computer storage apparatus are disclosed. A log-likelihood ratio handler is configured to provide an input log-likelihood ratio to the decoder, wherein the input log-likelihood ratio is one of: a uniform input log-likelihood ratio for all bits calculated based on an estimated raw bit error rate for a particular data unit, or a bit-based input log-likelihood ratio for each bit calculated based on a confidence value for a cell containing said each bit. The decoder of the electronic non-volatile computer storage apparatus is configured to decode encoded data at least partially based on the input log-likelihood ratio from the log-likelihood ratio handler.

    Abstract: An apparatus for decoding data includes a decoder circuit operable to apply a decoding algorithm to a decoder input to yield a codeword, a convergence detection circuit operable to determine whether parity checks are satisfied by the decoder input and to identify unsatisfied parity checks in the decoder circuit, and a symbol flipping controller operable to change values of at least one symbol in the decoder input based on information about the unsatisfied parity checks. The decoder circuit is restarted to process the decoder input with the changed values. The information about the unsatisfied parity checks is obtained at each of a number of local decoding iterations in the decoder circuit.
