  • Patent number: 9639337
    Abstract: An attribute group storage unit acquires and holds attribute groups set to respective data blocks. A scenario determination unit determines respective transfer systems of the respective blocks between a memory of the lowest hierarchy and a memory of another hierarchy based on those attribute groups and a configuration of an arithmetic unit which is the parallel processor, and controls the transfer of the respective data blocks according to the determined transfer systems, and the parallel arithmetic operation corresponding to the transfer. Each of the attribute groups is necessary to determine the transfer systems, and includes one or more attributes not depending on the configuration of the parallel processor. The attribute groups of the write blocks are set assuming that each of the write blocks has already been located in the memory of another hierarchy, and is transferred to the memory of the lowest hierarchy.

  • Patent number: 9620449
    Abstract: A portion-to-be-melted of a fuse is surrounded by plates, so that heat to be generated in a meltdown portion of the fuse under current supply can be confined or accumulated in the vicinity of the meltdown portion of the fuse. This makes it possible to facilitate meltdown of the fuse. The meltdown portion of the fuse in a folded form, rather than in a single here a fuse composed of a straight-line form, is more successful in readily concentrating the heat generated in the fuse under current supply into the meltdown portion, and in further facilitating the meltdown of the fuse.

  • Patent number: 9622245
    Abstract: When a state of a radio communication device corresponds to a predetermined state, a communication control unit operates in the first mode to communicate according to the BLE standard, while when the radio communication device does not receive connect request packets, the communication control unit operates in the second mode to communicate. A rewrite switching unit switches to a rewritable state when the communication control unit operates in the first mode and to a rewriting prohibited state when the communication control unit operates in the second mode. The first mode is a mode for updating. In the first mode, the communication control unit transmits a notification for limiting the communication to the updating in an establishment process of the communication. The second mode is a mode for performing processing other than the updating. In the second mode, the communication control unit does not transmit the notification.

  • Patent number: 9614081
    Abstract: A gate insulating film and a gate electrode of non-single crystalline silicon for forming an nMOS transistor are provided on a silicon substrate. Using the gate electrode as a mask, n-type dopants having a relatively large mass number (70 or more) such as As ions or Sb ions are implanted, to form a source/drain region of the nMOS transistor, whereby the gate electrode is amorphized. Subsequently, a silicon oxide film is provided to cover the gate electrode, at a temperature which is less than the one at which recrystallization of the gate electrode occurs. Thereafter, thermal processing is performed at a temperature of about 1000° C., whereby high compressive residual stress is exerted on the gate electrode, and high tensile stress is applied to a channel region under the gate electrode. As a result, carrier mobility of the nMOS transistor is enhanced.
