MEMORY SYSTEM WITH LDPC DECODER AND METHOD OF OPERATING SUCH MEMORY SYSTEM AND LDPC DECODER

A memory system, a bit-flipping (BF) low-density parity check (LDPC) decoder included in the memory system and operating methods thereof in which such decoder or decoding has a reduced error floor. Such a BF LDPC decoder is configured using a deep learning framework of trained and training neural networks and data separation that exploits the degree distribution information of the constructed LDPC codes.
