Abstract
A decoder includes circuitry and multiple Variable-Node Circuits (VNCs). The VNCs individually hold one or more variables of an Error Correction Code (ECC) that is representable by a plurality of check equations defined over the variables. The circuitry is configured to receive a code word including variables having m-bit values that was encoded using the ECC, to further receive reliability levels assigned respectively to the variables, to decode the code word by applying to the code word a sequence of iterations, including deciding in a given iteration whether a given VNC is to be processed or skipped in that iteration, depending on the reliability levels assigned to the variables of the given VNC, and, when the given VNC is selected for processing, to make a decision whether or not to update one or more of the variables of the given VNC, and to apply the decision by the given VNC.
