Configuring iterative error correction parameters using criteria from previous iterations

A method comprising:

• reading a sense word;
• executing a plurality of parity check equations on corresponding subsets of the sense word to determine a plurality of parity check equation results;
• determining a syndrome for the sense word using the plurality of parity check equation results;
• determining whether the syndrome for the sense word satisfies a codeword criterion;
• and
• responsive to the syndrome for the sense word not satisfying the codeword criterion, performing an iterative low density parity check (LDPC) correction process, wherein at least one iteration after a first iteration in the LDPC correction process uses a criterion based at least partially on a previous iteration or partial iteration, and wherein performing the iterative LDPC correction process comprises flipping any bits in the sense word having an associated energy level that is greater than or equal to a maximum energy level associated with any one bit of the sense word from the previous iteration.

A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

• reading a sense word from a memory device;
• executing a plurality of parity check equations on corresponding subsets of the sense word to determine a plurality of parity check equation results;
• determining whether the plurality of parity check equation results indicates an error in the sense word;
• and
• responsive to the parity check equation results indicating an error in the sense word:
• performing a first iteration of an error correction process;
• and
• performing one or more subsequent iterations of the error correction process, wherein the one or more subsequent iterations comprise flipping any bits in the sense word having a number of parity check equation results that are in an unsatisfied state equal to a maximum number of parity check equation results that are in the unsatisfied state for any one bit of the sense word from a previous iteration or partial iteration.
