Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for improving data integrity in a non-volatile memory system comprising: accessing non-volatile memory cells for retrieving hard data bits; decoding the hard data bits; and in response to a determination that decoding the hard data bits was not successful: generating soft information by capturing a reliability of the hard data bits, wherein generating the soft information includes loading a first read register with values of the hard data bits…
