The pin count largely determines the cost of a chip package, which is often comparable to the cost of a die. In 3D processor-memory designs, power and ground (P/G) pins can account for the majority of the pins. This is because packages include separate pins for the disjoint processor and memory power delivery networks (PDNs). Supporting separate PDNs and P/G pins for processor and memory is inefficient, as each set has to be provisioned for the worst-case power delivery requirements. In this… CONTINUE READING
