    摘要: A thyristor highly proof against dv/dt in which to prevent malignition due to the displacement current produced by the application of an abruptly rising forward voltage or the internal leakage current increasing with the temperature rise of the semiconductor substrate, an auxiliary electrode is provided to the intermediate region adjacent to one of the outermost regions of the semiconductor substrate to which two main electrodes, anode and cathode, are provided, the auxiliary electrode and the main electrode on the one outermost region being connected electrically, and a control region having the opposite conductivity type to that of the intermediate region is formed in the intermediate region between the auxiliary electrode and the main electrode on the one outermost region, the control region being provided with a gate electrode. By supplying a control signal to the gate electrode a depletion layer is produced in the intermediate region such that the path of the control signal from the gate electrode to the auxiliary electrode is completely blocked and the control signal is all utilized for the ignition. The displacement current and the leakage current are bypassed from the auxiliary electrode to the main electrode on the one outermost region.

    摘要: Each of processors has a barrier write register and a barrier read register. Each barrier write register is wired to each barrier read register by a dedicated wiring block. For example, a 1-bit barrier write register of a processor is connected, via the wiring block, to a first bit of each 8-bit barrier read register contained in the processors, and a 1-bit barrier write register of another processor is connected, via a wiring block, to a second bit of each 8-bit barrier read register contained in the processors. For example, a processor writes information to its own barrier write register, thereby notifying synchronization stand-by to the other processors and reads its own barrier read register, thereby recognizing whether the other processors are in synchronization stand-by or not. Therefore, a special dedicated instruction is not required along barrier synchronization processing, and the processing can be made at a high speed.

    摘要: A semiconductor data processor has a first memory(6) constituting a cache memory, a second memory(20) capable of being a cacheable area or a non-cacheable area by the first memory, and a read buffer(12) capable of carrying out an operation for outputting data corresponding to a read access when the second memory is read accessed as the non-cacheable area. The designation of the cacheable area and the non-cacheable area for the second memory is determined by the designation of a cacheable area or a non-cacheable area for a memory space to which the second memory is mapped. The designation may be carried out in the operation mode of the data processor or by setting a control register, for example.

    摘要: A lateral transistor having a high breakdown voltage and operable with an improved current amplification factor and an improved cut-off frequency comprises in a semiconductor substrate of one conductivity type, a base layer of the one conductivity type and an emitter layer of the other conductivity type formed in the base layer. A first collector layer of the other conductivity type is formed in the one principal surface of the substrate apart from the base layer and a second collector layer of the same conductivity type having an impurity concentration lower than that of the first collector layer is formed between the first collector layer and the base layer in contact with the latter layers. Emitter, base and collector electrodes make ohmic contact with the emitter, base and first collector layers respectively. The emitter electrode extends on a passivation film covering the one principal surface of the substrate to terminate at a point on the second collector layer.
