In an integrated circuit logic matrix the input conductors are provided in pairs, e.g. ce1, ce2, the conductors of each pair being connected to each output conductor, e.g. cs1, by a combination of two fuses fs1, fs2 and a coupling component such as a diode cl1. The output of the diode cl1 is connected to the output conductor cs1 while the input of the diode is connected through one fuse fs1 to the input conductor ce1 and through the second fuse fs2 to the other input conductor ce2 of the pair. One or both of the fuses in each pair may be blown prior to operation of the matrix, dependent upon the desired circuit function. In the embodiment the diodes cl1 &c. are all formed in a common Si body provided with deposited A1 conductors ce1, ce2, cs1 &c., and the fuses fs1, fs2 &c. comprise portions of conductors having reduced cross-section which may be melted as desired by relatively high currents applied between appropriate pairs of input and output conductors. |
