ABSTRACT:
A nonvolatile storage element of a single-layer gate type structure is arranged so that a floating gate is formed of a conductive layer which partly overlaps with a control gate, formed of a diffused layer, and is provided with a barrier layer covering a part of or the whole surface of the floating gate. Nonvolatile storage elements characterized as such are used for redundancy control of defects or change of functions.
