ABSTRACT:
A non-volatile semiconductor memory device includes a semiconductor substrate, and a source and a drain of a MOS transistor formed on one surface of the semiconductor substrate and spaced about from each other. First, second and third gates are formed on one side of the substrate through an insulating film and between the source and the drain of the MOS transistor. This memory device has one transistor construction and can be fabricated simply and finely.
