    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: A storage system and method for interleaving a plurality of logical sectors in the storage system is disclosed. The method includes: dividing each logical sector into a predetermined number of slices; sequentially indexing the logical sectors, wherein each logical sector is identified by a logical sector index; sequentially indexing the predetermined number of slices in each logical sector, wherein each slice of the predetermined number of slices is identified by a slice index within each logical sector; and interleaving the logical sectors according to a slice interleaving process. The interleaving step further includes: a) identifying a first indexed slice of a first indexed logical sector as an initial slice; and b) identifying a subsequent slice by advancing the slice index to a subsequent index in the slice index sequence and advancing the logical sector index to a subsequent index in the logical sector index sequence.
