1. A device comprising
a support having electrical connection sites at a surface thereof, and a stacked die assembly mounted onto the surface and electrically connected to one or more of the connection sites, wherein each die in the stacked die assembly has peripheral interconnect terminals each interconnect terminal electrically coupled with a die pad of a die of the stacked die assembly at an active side of the die and each interconnect terminal is disposed at or overlying the active side of the die to which the interconnect terminal is coupled, wherein a plurality of die in the stack are electrically interconnected by a same line or a same trace of an electrically conductive polymer or an electrically conductive ink, and wherein the line or the trace of the electrically conductive polymer or the electrically conductive ink contacts the peripheral interconnect terminals on each of the respective electrically interconnected plurality of die, wherein the active side of at least a first die in the stack faces in a first direction, and the active side of at least a second die faces in a second direction, opposite the first direction.
