摘要： There are provided a bipolar-MOS IC device smaller than half-micron scale, and a combination of such IC device and external circuits. The IC device has an internal voltage generating circuit for generating an internal power source by using an external power source, the voltage of the internal power source being lower than that of the external power source. The internal voltage generating circuit includes an NPN transistor formed in an N-type region or N-type island within a P-type semiconductor substrate of the IC device, and a PMOS transistor formed in the N-type island. The collector of the NPN transistor and the source of the PMOS transistor are used as external power source terminals. The drain of the PMOS transistor is connected to the base of the NPN transistor. The gate is used as a control signal terminal. The emitter of the NPN transistor is used as an internal power source output terminal. A current path from the external power source input terminal and the internal power source output terminal is accordingly formed within the N-type island isolated from the P-type substrate.

摘要： A microprocessor according to the present invention comprises a sub-read bus, to which output terminals of registers of a register file of the microprocessor are coupled. The sub-read bus is in turn coupled to a main read bus of the microprocessor through a bus output circuit. Upon occurrence of a read access to any of the registers, the bus output circuit couples the sub-read bus with the main read bus, whereby data read out from the registers to the sub-read bus are transmitted to the main read bus, and under no existence of the read access, the bus output circuit interrupts the data transmission from the sub-read bus to the main read bus. With this, a load capacitance of the read bus is reduced. As a result, a time for making access to the read bus is much improved.
