1. A programmable interconnect structure to couple a first node to a second node for an integrated circuit comprising:

  • a power voltage and a ground voltage; and

    a pull-up circuit coupled between said power voltage and said node; and

    a pull-down circuit coupled between said ground voltage and said second node; and

    a programmable circuit coupled to said first node and to each of said pull-up and pull-down circuits; and

    a configuration circuit including at least one memory element coupled to said programmable circuit, wherein altering the data in said at least one memory element provides a programmable method of;

    decoupling said first node from second node by deactivating both said pull-up and pull-down circuits; and

    coupling said first node to second node compelled by activating said pull-up and pull-down circuits.
