A non-volatile semiconductor memory device has a semiconductor substrate, an element isolation region disposed in a surface of the semiconductor substrate, a well region disposed along one principal surface of the semiconductor substrate, source and drain regions arranged in the well region, a gate oxide film arranged on the surface of the semiconductor substrate between the source region and the drain region, a floating gate disposed on the gate oxide film, and an insulating film disposed on a surface of the floating gate. A control gate is capacitively coupled to the floating gate disposed through intermediation of the insulating film. A resistive element is serially connected to the control gate. Write characteristics of the non-volatile semiconductor memory device are improved as a result of a delay effect of the resistive element serially connected to the control gate.
