METHOD AND SYSTEM FOR IMPROVING DATA INTEGRITY IN NON-VOLATILE STORAGE

摘要

A method (700) for improving data integrity in a non- volatile memory system (100) includes: accessing a non-volatile memory cell (202) for retrieving hard data bits (212); generating soft information (218) by capturing a reliability of the hard data bits (212); calculating syndrome bits (222) by applying a lossy compression (220) to the soft information (218); and generating a host data (104) by executing a low density parity check (LDPC) iterative decode (128) on the hard data bits (212) and the syndrome bits (222).
