Abstract

A mask-programmable logic macro includes at least three input terminals an output terminal and a first set of transistors comprised of at least three transistors formed on a semiconductor substrate, each of the transistors comprising a controllable path and a control terminal. The controllable paths can be connected in series with one another between a first supply terminal and the output terminal by metallizing first metallization regions. The the transistors of the first set of transistors are arranged on the semiconductor substrate in such a way that at least one controllable path of the transistors can be bridged by metallizing one of the first metallization regions. A respective of the input terminals can be connected to a respective of the control terminals by metallizing a second metallization region.
