Abstract
The floating-gate coupling noise is a major cause of errors in the multi-level cell (MLC) NAND flash memory. In this paper, we propose a coupling canceller maximum-likelihood (CCML) detection for improving the read performance in the MLC NAND flash memory. It estimates the trellis target values of the Viterbi detector during the training. The proposed scheme performs better than conventional threshold detections with and without the coupling canceller on the MLC NAND flash memory.
