Abstract

1483555 Field effect transistors SIEMENS AG 22 Aug 1975 [20 Sept 1974] 34866/75 Heading H1K A FET for use as a storage element has a floating gate G and a channel K containing an inhomogeneous region V which accelerates charges into the gate G which charges up accordingly. The inhomogeneity may be produced by one or more tapered or constricted channel zones produced by shaping the gate electrode G appropriately and/or by variations in the thickness of the gate insulation A. The channel K may be P or N type and the transistor operated in the enhancement or depletion mode, and an external electrode GHA may be capacitively coupled to the gate electrode G.
