 | Balasubramonian, Rajeev | Quantifying the relationship between the power delivery network and architectural policies in a 3D-stacked memory device | Many of the pins on a modern chip are used for power delivery. If fewer pins were used to supply the same current, the wires and pins used for power delivery would have to carry larger currents over longer distances.
