Abstract
A NAND flash memory device is recovered by applying a predetermined bias to a drain or a source. A negative bias is applied to a cell gate so that electrons are injected into a floating gate of a cell. This narrows the distribution of an erase threshold voltage and minimizes interference from states of peripheral cells.
