Abstract
Systems and methods are provided for generating a soft information metric corresponding to a bit stored in a memory. The systems and methods include comparing a symbol value associated with the stored bit to a plurality of decision thresholds to obtain a plurality of binary values. One of the plurality of binary values is selected to obtain a reference value. Further, a frequency metric is computed, which corresponds to the number of times each of the plurality of binary values equals a predefined value. The soft information metric is then determined based on the frequency metric and the reference value.
