ABSTRACT:
A monolithically integrated circuit has circuit portions which are selectively connectible and disconnectible by switch elements from remaining portions of the integrated circuit. The switch elements are comprised of integrated field effect transistors in MIS technology with a gate insulating layer. By use of an electron beam, gate layers in some of the transistors can be selectively charged so as to cause a shift in a threshold voltage of those transistors. In this fashion, these transistors can assume a first switching state while the remaining transistors are in a second switching state when a potential is applied to the circuit.
