ABSTRACT:
A universal logic module of a programmable semiconductor device is constructed by first, second, third, fourth and fifth terminals, a first transfer gate connected between the first and fourth terminals, a second transfer gate connected between the second and fourth terminals, and an inverter connected between the third and fifth terminals. The first and second transfer gates are controlled by voltages at the third and fifth terminals, so that one of the first and second transfer gates is turned ON and the other of the first and second transfer gates is turned OFF.
