A data processing system, circuit arrangement, integrated circuit device, program product, and method utilize source identification information to selectively route data to different memory sources in a shared memory system. This permits, for example, data to be routed to only a portion of the memory sources associated with a given requester, thereby reducing the bandwidth to other memory sources and reducing overall latencies within the system. Among other possible information, the source identification information may include an identification of which memory source and/or which level of memory is providing the requested data, and/or an indication of what processor/requester and/or what type of instruction last modified the requested data.
