Claim One:
1. A method for decoding data, comprising: providing decoder circuitry in communication with a plurality of variable nodes and a plurality of check nodes, wherein each of the variable nodes is connected to the plurality of check nodes, and each of the check nodes is connected to the plurality of variable nodes; receiving, at the decoder circuitry during a first iteration, a value for each of the plurality of variable nodes; determining, at the decoder circuitry during a second iteration, an indication for each of the plurality of check nodes based on the value received during the first iteration by connected variable nodes; and updating, at the decoder circuitry during the second iteration, the value of each of the variable nodes based on (1) the value received during the first iteration, and (2) the indication determined during the second iteration of each of the plurality of connected check nodes; wherein the value of each of the plurality of variable nodes is selected from a group consisting of at least four values, and wherein the indication for each of the plurality of check nodes is selected from a group consisting of at least five indications.
