Abstract
A method for improving data integrity in a non-volatile memory system includes: accessing a non-volatile memory cell for retrieving hard data bits; generating soft information by capturing a reliability of the hard data bits; calculating syndrome bits by applying a lossy compression to the soft information; and generating a host data by executing a low density parity check (LDPC) iterative decode on the hard data bits and the syndrome bits.
