Abstract
A flash memory device and method of fabricating the same, wherein a width at the top of a floating gate is narrower than that at the bottom of the floating gate. The area of the floating gate can be reduced while maintaining the overlap area between the control gate and the floating gate. Therefore, inter-cell interference can be reduced without lowering program speed.
