1. An apparatus comprising:
- a die comprising an interior portion and an exterior portion, wherein the interior portion comprises;
a first circuit formed in a first area of the interior portion;
a second circuit formed in a second area of the interior portion; and
a third circuit formed in a third area of the interior portion, the first circuit separate from the second circuit or the third circuit; and
wherein the exterior portion comprises;
a first trace coupling the first circuit to a first conductive structure supported by the exterior portion of the die;
a second trace coupling the second circuit to a second conductive structure supported by the exterior portion of the die; and
a third trace coupling the third circuit to a third conductive structure supported by the exterior portion of the die; and
a package encasing the die and supporting, via an internal surface of the package, an interconnect layer that is external to the die, the interconnect layer electrically connecting the first, second, and third conductive structures effective to distribute signals generated by the first circuit to the second and third circuits, the signals generated by the first circuit remaining within the package encasing the die.

Abstract
Various aspects of an approach for routing die signals in an interior portion of a die using external interconnects are described herein. The approach provides for contacts coupled to circuits in the interior portion of the die, where the contacts are exposed to an exterior portion of the die. The external interconnects are configured to couple these contacts so that signals from the circuits in the interior portion of the die may be routed externally to the die. In various aspects of the disclosed approach, the external interconnects are protected by a packaging for the die.
