Data stored in non-volatile storage is decoded using iterative probabilistic decoding. An error correcting code such as a low density parity check code may be used. In one approach, initial reliability metrics, such as logarithmic likelihood ratios, are used in decoding sensed states of a set of non-volatile...http://www.google.es/patents/US8145981?utm_source=gb-gplus-sharePatente US8145981 - Soft bit data transmission for error correction control in non-volatile memory
