Abstract
For a selection of semiconductor chips stacked on top of one another, the invention includes leading through selection contact points of one chip on a rear side thereof and connecting them to corresponding selection contact points of the other semiconductor chip. Programmable input amplifiers are programmed to be transmissive or blocking through fuses/antifuses so that selection signals applied to the selection contact points either activate or block functional elements only of one or only of the other semiconductor chip. As a result, simple stacking of identically prefabricated semiconductor chips is made possible.
