ABSTRACT:
A semiconductor memory device having a MOS transistor with a floating gate capable of storing data.
The MOS transistor has an erase gate which overlaps part of the floating gate with an insulating film interposed therebetween. Upon application of a high voltage on the erase gate, the field emission is caused between the floating gate and the erase gate and the charge stored on the floating gate is removed.
