  • Abstract
    The mechanism of anomalous leakage current (ALC) which induces anomalous retention failure in flash memory devices has been studied utilizing the modified floating gate technique. Based on the model, a new prediction method for retention failure rate has been proposed, which realizes drastic shortening of the quality assurance approaches.
