  • Patent number: 9159647
    Abstract: 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.

  • Patent number: 9055498
    Abstract: Described embodiments provide for handover in a long term evolution (LTE) communication network. A LTE macrocell base station may receive a measurement report from user equipment while providing a communication service to the user equipment located within a service area of the LTE macrocell base station, and determine whether or not the neighbor cell is a LTE macrocell or a LTE femtocell based on the measurement report. The LTE macrocell base station may initiate hand-over of the user equipment to a neighbor WCDMA macrocell base station when the neighbor cell is determined as the LTE femtocell.
