A method and apparatus to adaptively validate a physical net routing topology of a substrate design to a target topology of the substrate design. A user inputs offer parameters for a new initiative. The supplied data packets are delivered to a first requesting network device and when an additional network request for the data packets is made by a second requesting network device the data packets are delivered from the memory device to the second requester in response to the additional network request without interrupting the slave computing device to redundantly supply the data packet. Thus, the visited network is capable of dynamically classifying incoming roaming traffic and intelligently routing the traffic according to the service characteristics of the traffic flow for each subscriber, e. The memory architecture includes separately controlled refresh and sense amplifiers to enable a memory access and refresh cycle simultaneously. Material of the semiconductor substrate may be removed from the second surface to expose a portion of the conductive material filling the at least one opening.
