Abstract: The present invention relates to a flash memory cell. The type and concentration of an impurity injected into a floating gate and a polysilicon layer for a control gate is controlled so that upon an erase operation, as a threshold voltage is reduced, a depletion layer is formed in a first polysilicon layer, discharge of electrons is increasingly reduced as the threshold voltage reaches a target voltage and discharge of the electrons is stopped at the target voltage. Therefore, over erase of the flash memory cell is prevented. Malfunction of the cell due to over erase is prevented and reliability and an electrical characteristic of the erase operation can be improved by distributing threshold voltages of all the cells to target voltages.

Abstract: A method of erasing a flash memory device performs erase operation by hot carrier injection method, by applying a ground potential to a source and applying the bias from a high voltage to a low voltage step by step, with a voltage of 5V being applied to a drain, wherein the bias of a floating gate in the flash memory device keeps 1.8 through 2V. being hot carrier injection condition and wherein the gate bias adjusts the bias applied according to the coupling ratio. Thus, it can reduce the erase time and allows the erase on a byte basis.

Abstract: 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.
