Abstract
A circuit is provided to isolate a contact pad from a logic circuit of a die once the contact pad is no longer needed. This circuit can take many forms including a CMOS multiplexer controlled by a fuse or anti-fuse, an NMOS or PMOS pass gate controlled by a fuse or anti-fuse, or even a fusible link which is severed to effect isolation. Additionally, a circuit is provided that switchably isolates one of two contact pads from a logic circuit.
