A new three-terminal switching device

A new switching device has been conceived and reduced to practice. This device is a once-programmable three-terminal fuse (TTF) with an on-resistance of a good metallic conductor and an off-resistance which is essentially infinite. In the new structure the fusible circuit path is fully isolated from a control electrode both before and after programming. We discuss the basic concept of the TTF and highlight some of its possible applications.<
