Abstract: Disclosed herein are integrated circuit (IC) die stacks, as well as related apparatuses and methods. For example, in some embodiments, an IC package may include: a package substrate having a substrate conductive contact; a first die coupled to the package substrate, wherein the first die has a first face and an opposing second face, the second face of the first die is between the first face of the first die and the package substrate, and the first die has a first conductive contact at the first face of the first die; a second die coupled to the first die, wherein the second die has a second conductive contact facing the first face of the first die; and a bondwire between the first conductive contact and the substrate conductive contact, wherein the bondwire is also in electrical contact with the second conductive contact.
