Stopping criteria for layered iterative error correction

摘要

The present disclosure includes apparatuses and methods related to stopping criteria for layered iterative error correction. A number of methods can include receiving a codeword with an error correction circuit, iteratively error correcting the codeword with the error correction circuit including parity checking the codeword on a layer-by-layer basis and updating the codeword after each layer. Methods can include stopping the iterative error correction in response to a parity check being correct for a particular layer.

1. A method, comprising:
receiving a codeword with an error correction circuit; iteratively error correcting the codeword with the error correction circuit including: parity checking the codeword on a layer-by-layer basis, wherein a layer comprises a fraction of an iteration; and updating the codeword after each layer; and
stopping the iterative error correction in response to a parity check being correct for a particular layer of a particular iteration without error correcting a next layer of the particular iteration, wherein the particular layer is a fraction other than a last fraction of the particular iteration, and wherein the parity check being correct for the particular layer comprises the parity check resulting in less than a threshold number of parity errors.
