    摘要: A semiconductor integrated circuit device is arranged to have a plurality of logic circuit blocks, a data signal path for interconnecting logic circuit blocks and for providing a function of interfacing a current-driven signal. The logic circuit block on a signal output side includes an output circuit connected to the data signal path and a switching element formed of an NMOS transistor for controlling current flowing through the data signal path in response to an input signal applied to an input terminal of the output circuit. The logic circuit block on a signal input side includes an input circuit connected to the data signal path. The input circuit includes a bipolar transistor having an emitter connected to a constant current source, a collector forming an output terminal, and a base set at a fixed potential. The data signal path led from the output circuit is connected to the emitter of the bipolar transistor. The arrangement results in reducing a signal amplitude on the signal bus, thereby speeding up the transmission of the data signal and reducing noise of the signal.

    摘要: A semiconductor memory comprises a write driver which is provided to correspond to respective data line and by which data lines connected with a memory cell through the control of a word line are driven in a write operation. The write driver includes MOSFETs of first group and MOSFETs of second group. In a case where a write enable signal does not designate the write operation, the MOSFETs of the first group are normally in ON states to pull up the data lines. Besides, in a case where the write enable signal designates the write operation, each of them operates in accordance with the value of input data, to maintain the ON states and pull up the corresponding data line in case of driving the data line to a "high" level and to fall into OFF states in case of driving the data line to a "low" level. On the other hand, the MOSFETs of the second group are normally in OFF states. Besides, in the case where the write enable signal designates the write operation, each of them operates in accordance with the value of the input data, to fall into ON state and draw the corresponding data line to the low level in the case of driving the data lines to the low level.

    摘要: In an input level converter for TTL-CMOS level conversion (or other conversion to CMOS) for an internal logic block operating with CMOS levels, an output transistor for executing the charge or discharge of the output capacitance thereof is formed of a bipolar transistor. Thus, the propagation delay times and their capacitance-dependencies of the input level converter can be lessened. Similarly, in an output level converter for CMOS-TTL level conversion (or other conversion from CMOS) for the internal logic block operating with the CMOS levels, an output transistor for executing the charge or discharge of the output load capacitance thereof is formed of a bipolar transistor. Thus, the propagation delay times and their capacitance-dependencies of the output level converter can also be lessened.

The circuit has a resistor provided between the input terminal and/or the output terminal and one of the at least one semiconductor devices and an electronic switch connected in parallel with the resistor. The electronic switch is on-off controlled so as to exhibit a relatively low impedance when the semiconductor device is in operation and a relatively high impedance when the semiconductor device is not in operation. Thus, the semiconductor integrated circuit device is operable at a higher speed with an improved reliability and/or with controllable response characteristics, as compared with the conventional device.
