A method of bandwidth optimization in a non-volatile memory system includes: retrieving hard data bits; generating soft information from the hard data bits; applying a lossless compression to the soft information for calculating syndrome bits; and executing a low density parity check (LDPC) iterative decode on the hard data bits and the syndrome bits.

Bandwidth optimization in a non-volatile memory system

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.
