The requesting authority retains control over the content of the emergency message and can trigger the implementation of the broadcast from a variety of signal interfaces.
Method for suppression of multicast join/prune messages from extranet receivers
A method of suppressing the number of PIM messages from extranet receivers is disclosed. Each receiver, before sending a PIM message, first searches for any other receivers other than itself. If there are no other receivers, then the PIM message is sent; otherwise, the receiver suppresses sending the PIM message. PIM Join, triggered Join, and Prune messages may be suppressed. If there are multiple receivers, the PIM messages are sent by a source Extranet receiver located in a provider edge router, for example. The receiver sends the PIM messages for the rest of the Extranet receivers in the provider edge router, and also maintains a counter, ensuring that only one PIM message is sent within a specified time period. As a result, the number of PIM messages traversing core elements of a service provider network may be greatly reduced.

Resistance change memory device
A resistance change memory device including: a substrate; cell arrays stacked thereabove, each including a matrix layout of memory cells; a write circuit configured to write a pair cell constituted by two neighboring memory cells; and a read circuit configured to read complementary resistance value states of the pair cell as one bit of data, wherein the memory cell includes a variable resistance element for storing as information a resistance value, and wherein the variable resistance element has a recording layer formed of a first composite compound expressed by AxMyOz (where “A” and “M” are cation elements different from each other; “O” oxygen; and 0.5≦x≦1.5, 0.5≦y≦2.5 and 1.5≦z≦4.5) and a second composite compound containing at least one transition element and a cavity site for housing a cation ion.
The object of the invention is to avoid an unselected data line being driven in a memory array composed of memory cells each of which uses a storage element depending upon variable resistance and a selection transistor when the selection transistors in all memory cells on a selected wordline conduct. To achieve the object, a source line parallel to a data line is provided, a precharge circuit for equipotentially driving both and a circuit for selectively driving the source line are arranged. Owing to this configuration, a current path is created in only a cell selected by a row decoder and a column decoder and a read-out signal can be generated. Therefore, a lower-power, lower-noise and more highly integrated nonvolatile memory such as a phase change memory can be realized, compared with a conventional type.
