  • Method and apparatus for communicating data and program thereof
    Publication number: 20080082632
    Abstract: A server assigns one of a plurality of clients as a representative client to each of a plurality of block data in a round-robin manner, for example. The server transmits the block data and information indicating the representative client assigned to the block data to the plurality of clients by multicast communication. The representative client transmits a response acknowledgement to the server. When the server receives the response acknowledgement, the server transmits block data following the block data and information indicating a new representative client assigned to the following block data to the plurality of clients by multicast communication.

  • Interface device and topology formation method
    Publication number: 20080080490
    Abstract: When a loop connection associated with a port is detected while the port is in an Untested state ST3, a state machine corresponding to the port shifts from the state ST3 to a Loop_disabled state ST4. The state machine then shifts from state ST4 to a Sleep1 state ST5 while maintaining a Loop_disabled value set at 1. When the state machine in state ST5 detects a bus reset, the state machine shifts from state ST5 to state ST4. Subsequently, the bus reset detection further shifts the state machine from state ST4 to state ST3.

  • Tunnel magnetoresistance element, magnetic head, and magnetic memory
    Publication number: 20080080102
    Abstract: A TMR element is provided which has a large MR ratio. The TMR element has a tunnel barrier layer formed between a magnetization fixed layer and a magnetization free layer, and a cap layer disposed on the magnetization free layer. The tunnel barrier layer is formed of an MgO film. The magnetization free layer is formed of a CoFeB film. The cap layer is formed by forming a Ti film immediately above the CoFeB film such that the Ti film is in contact with the CoFeB film. This makes it possible to largely enhance the MR ratio of the TMR element. Further, by using the TMR element for a magnetic head and an MRAM, it is possible to improve the performance of magnetic heads and MRAMs.
