Abstract
This application is directed to error correction for data stored in a memory device. In response to a request to validate a block of data, the memory device identifies a set of check nodes corresponding to a set of variable nodes that represent the block of data. First check node values of the check nodes are determined based on the block of data, and stored in first registers. The memory device implements a plurality of iterations of error correction by flipping a subset of variable nodes successively during each iteration; determining second check node values of the check nodes; and updating the first check node values stored in the first registers based on the second check node values once in each of a first set of iterations and successively with flipping of each variable node in a second set of iterations following the first set of iterations.
