Abstract:
A multi-chip device and method of stacking a plurality substantially identical chips to produce the device are provided. The multi-chip device, or circuit, includes at least one through-chip via providing a parallel connection between signal pads from at least two chips, and at least one through-chip via providing a serial or daisy chain connection between signal pads from at least two chips. Common connection signal pads are arranged symmetrically about a center line of the chip with respect to duplicate common signal pads. Input signal pads are symmetrically disposed about the center line of the chip with respect to corresponding output signal pads. The chips in the stack are alternating flipped versions of the substantially identical chip to provide for this arrangement. At least one serial connection is provided between signal pads of stacked and flipped chips when more than two chips are stacked.
