Abstract
Memory systems may include a memory storage, and an error correcting code (ECC) unit suitable for determining a number of unsatisfied check nodes of a channel output in a decoding iteration of a decoding process, updating a flipping indicator of a variable node, comparing the flipping indicator of the variable node with a flipping threshold associated with the decoding process, flipping a bit of the variable node when the flipping indicator is greater than the flipping threshold, and ending the decoding process when decoding is determined to be successful or a maximal iteration number is reached.
