Abstract:
An apparatus and a method for reading from a non-volatile memory whereby soft decision data is used to determine the reliability of hard decision data. The hard decision data read from the non-volatile memory is de-randomized and the soft decision data read from the non-volatile memory is not de-randomized. Using the soft decision data, the hard decision data is decoded.
