Abstract
A non-volatile memory controller includes a hard-decision Low Density Parity Check (LDPC) decoder with a capability to dynamically select a voting method to improve the decoding in low bit error rate (BER) situations. The hard-decision LDPC decoder dynamically selects a voting method associated with a strength requirement for bit flipping decisions. In one implementation, the voting method is selected based on the degree of a variable node and previous syndrome values.
