Abstract: A system for decoding data stored in a non-volatile storage device may include processing circuits configured to decode, in a first iteration, each of a plurality of component codes corresponding to the data by performing a first number of enumerations over hypotheses. The processing circuits may be configured to determine, in the first iteration, an extrinsic value output for each of the component codes based on log-likelihood ratios (LLRs) of one or more error bits of a codeword. The processing circuits may be configured to determine a second number of enumerations based on the extrinsic value. The processing circuits may be configured to decode, in a second iteration, each of the plurality of component codes by performing the second number of enumerations over hypotheses.
