A technique for programming connections of conductors that is particularly adapted to be implemented as part of an integrated circuit so that a number of connections internal of the circuit can be made from outside the circuit in order to customize it after fabrication. A specific arrangement of five switching transistors is particularly advantageous for each cross-point of two conductors to be connected together in one of many possible ways. The desired switching arrangement at each cross-point may be programmed by use of the same conductors being interconnected to carry control signals from outside the circuit to a memory associated with each cross-point switching circuit. While these memories are being programmed, each cross-point is temporarily forced to a desired state for communicating the control signals from outside the circuit to the memories.
