Abstract: Systems, among other embodiments, include topologies (data and/or control/address information) between an integrated circuit buffer device (that may be coupled to a master, such as a memory controller) and a plurality of integrated circuit memory devices. For example, data may be provided between the plurality of integrated circuit memory devices and the integrated circuit buffer device using separate segmented (or point-to-point link) signal paths in response to control/address information provided from the integrated circuit buffer device to the plurality of integrated circuit buffer devices using a single fly-by (or bus) signal path. An integrated circuit buffer device enables configurable effective memory organization of the plurality of integrated circuit memory devices. The memory organization represented by the integrated circuit buffer device to a memory controller may be different than the actual memory organization behind or coupled to the integrated circuit buffer device.

Abstract: Described are mobile phones that incorporate radiation detectors formed using commonly available semiconductor memories. The radiation detectors require little or no additional hardware over what is available in a conventional phone, and can thus be integrated with little expense or packaging modifications. The low cost supports a broad distribution of detectors. Data collected from constellations of detector-equipped mobile phones can be used to locate mislaid or stolen nuclear materials or other potentially dangerous radiation sources. Phone users can be alerted to radiation dangers in their vicinity, and aggregated phone-specific error data can serve as user-specific dosimeters.
