Protograph QC-LDPC and Rate-Adaptive Polar Codes Design for MLC NAND Flash Memories

A protograph-based quasi-cyclic (QC) low-density parity-check (LDPC) code for multi-level cell (MLC) NAND flash memories is proposed in this paper. In this design approach, the quantized voltage signals are measured for soft decoding because the exact voltage values are unavailable. Flash memory cha...
