Abstract
Low-density parity-check (LDPC) coding based on memory cell voltage distribution (CVD) in data storage devices. In one embodiment, a memory controller includes a memory interface configured to interface with a non-volatile memory; and a controller. The controller is configured to receive a plurality of data pages to be stored in the non-volatile memory, and transform the plurality of data pages into a plurality of transformed data pages. The controller is further configured to determine a plurality of parity bits based on the plurality of transformed data pages, and store the plurality of data pages and the plurality of parity bits in the non-volatile memory.
