Low density parity check decoder for irregular LDPC codes
(United States. Patent and Trademark Office, 2013-10-08)
A method and system for decoding low density parity check (“LDPC”) codes. An LDPC decoder includes a control unit that controls decoder processing, the control unit causing the decoder to process the blocks of a low density ...
Low density parity check decoder
(United States. Patent and Trademark Office, 2015-08-18)
A method and system for decoding low density parity check (“LDPC”) codes. An LDPC decoder includes an R select unit, a Q message first-in first-out (“FIFO”) memory, and a cyclic shifter. The R select unit provides an R ...
Low density parity check decoder
(United States. Patent and Trademark Office, 2018-11-27)
A method and system for decoding low density parity check (“LDPC”) codes. A method and system for decoding low density parity check (“LDPC”) codes. An LDPC code decoder includes decoding circuitry configured to process ...
Asymmetric error correction and flash-memory rewriting using polar codes
(United States. Patent and Trademark Office, 2019-08-13)
Techniques are disclosed for generating codes for representation of data in memory devices that may avoid the block erasure operation in changing data values. Data values comprising binary digits (bits) can be encoded and ...
Rank-modulation rewriting codes for flash memories
(United States. Patent and Trademark Office, 2015-07-21)
Rank modulation has been recently proposed as a scheme for storing information in flash memories. Three improved aspects are disclosed. In one aspect the minimum push-up scheme, for storing data in flash memories is provided. ...
