    摘要: There is disclosed a method of erasing a flash memory device. The present invention implements a dummy recovery operation after a recovery operation for recovering the threshold voltage of an over-erased memory cell is implemented. Therefore, it can reduce the flow of the leakage current through bit lines to thus improve the program characteristic of the device.
