Abstract: The semiconductor device comprises a substrate, a channel layer formed on the substrate, a first barrier layer formed on the channel layer, being an indirect transition semiconductor layer containing Al and P and being not lattice-matched with the substrate, and an electrode formed above the first barrier layer. The first barrier layer having a wide band gap and having a high barrier to electrons is formed below the electrodes, whereby a high gate turn-on voltage can be available.

Abstract: In a distributed database system including a plurality of database systems each having a database, wherein a database possessed by one of the database systems serves as an original database, and databases of the remaining database systems are produced by replicating the original database, the presence or absence of update contention of the same data in two database systems is detected. When data susceptible to detection of update contention is updated, an update serial number is produced for the data. The update serial number includes a system identifier for identifying a database system in which the data is updated and an update frequency related to the number of times of updates. The update serial number is accumulatively stored in an update serial number history associated with the data each time the data is updated. When the updated data and the update serial number history associated therewith are transferred to a receiving database system, the contents of the update serial number history associated with the received data is compared with the contents of an update serial number history associated with data corresponding to the received data (target data) in a database of the receiving database system, and a contending state of the received data with the target data is determined based on the result of the comparison in the receiving database system.

Abstract: A push-pull type output circuit is used in the differential amplifier of a voltage converter circuit. The threshold voltage of the driving transistor is set lower than the voltages of the transistors of the other circuits to operate the differential amplifier at a voltage higher than the power supply voltage. By using the push-pull type output circuit, the amplitude increases and it is possible to raise the capacity of the driving transistor. Moreover, by setting the threshold voltage of the driving transistor of the buffering circuit lower than the threshold voltages of the transistors of the other circuits, it is possible to further raise the driving capacity. Increase of the sub-threshold current due to lowering of the threshold voltage can be prevented by operating the differential amplifier at a voltage higher than the power supply voltage.

Abstract: In a semiconductor memory, switch circuits are provided so as to inhibit voltage and signal supplies to each of the normal memory blocks when so required. On the other hand, a ROM is provided on the chip so as to store the address of a defective memory block which consumes an excessively large stand-by current when the semiconductor memory is in the stand-by mode. The switch circuits are controlled by the output of the ROM so as to inhibit the voltage and signal supply to the defective memory block. Then, a spare memory block which is substituted for the defective normal memory block receives the voltage and signal supply.
