Semiconductor devices with package-level configurability
A semiconductor device assembly includes a substrate and a die coupled to the substrate. The die includes a first contact pad electrically coupled to a first circuit on the die including at least one active circuit element, and a second contact pad electrically coupled to a second circuit on the die including only passive circuit elements. The substrate includes a substrate contact electrically coupled to both the first and second contact pads. The semiconductor device assembly can further include a second die including a third contact pad electrically coupled to a third circuit on the second die including at least a second active circuit element, and a fourth contact pad electrically coupled to a fourth circuit on the second die including only passive circuit elements. The substrate contact can be electrically coupled to the third contact pad and electrically disconnected from the fourth contact pad.
