Abstract
PURPOSE:To simplify a memory cell structure by generating the capture center of electrons at a gate insulating film compulsorily, thereby causing its center to capture the electrons. CONSTITUTION:A memory cell has a substrate; for example, a p-type silicon substrate as a semiconductor substrate 11 and regions, for example, n<+> type source and drain regions 12 and 13 are formed at the surface of the above silicon substrate and further, on these regions 12 and 13 a gate electrode 15 is formed through a gate insulating film 14 consisting of SiO2 and the like. Then the prescribed voltage which is impressed on the gate electrode 15 makes the capture center of electrons develop in the gate insulating film 14 and permits its center to accumulate electric charge so as to keep the information of memory. A memory cell structure is simplified in this way.
