1. A method for determining soft data from a hard read, comprising: determining a probability of a voltage, Vt, read from a memory cell given each of a number (N L ) of state voltage distributions (V L ) in the memory cell; and computing a log-likelihood ratio (LLR) for each digit in a data value corresponding to each of the N L state voltage distributions (V L ) in the memory cell based, at least partially, on a ratio of a sum of conditional probabilities of a b th digit of an L th state being a first value versus a second value, wherein a sign of the LLR is determined from a hard read of the memory cell.
