摘要:
A method, system and apparatus for connecting multiple memory device dies 51-54 to a substrate 56 which requires no trace between dies. A first embodiment assigns the connections of a memory device die 51 to be matched with other memory device dies 52-54 when mounted in staggered formation on the both sides of a substrate. The result is a daisy chained array connecting multiple integrated circuits with reduced capacitive loading. The capacitive loadings on the buses 57,58 between memory device dies 51,52,53 are reduced. The number of vias 57,58,59 is reduced because two stubs on the both sides of the substrate share one via. Another embodiment FIG. 7 arranges the dies in a closed loop.
