    摘要: In order to increase the speed, reduce the number of components and lower power consumption in a sense amplifier circuit for reading data held in a selected memory cell, current difference appearing on a data line is converted to potential difference directly by a current mirror circuit in accordance with data held in a selected memory cell. This current mirror circuit includes a diode for clamping the potential of the data line, and a transistor which is connected with this diode in a current mirror arrangement. A sense current flows through the diode in accordance with the data held in the selected memory cell, a corresponding current flows through the transistor by a current mirror operation, and the sense current is monitored. The monitored sense current is converted to a voltage signal indicating data of the selected memory cell.

    摘要: A CMOS gate circuit constituting the input stage of a semiconductor logic circuit includes a p channel MOS transistor supplied with current from a first power supply potential Vdd for charging an output signal line to a high level potential, a diode provided between MOS transistor and output signal line, an n channel MOS transistor supplied with current from a second power supply potential Vss responsive to an input signal (Vin) for discharging the potential of output signal line, and a diode provided between MOS transistor and output signal line. An input signal potential applied to input stage has its logic amplitude set to be Vdd-Vf to Vf. Vf represents the forward voltage of the diodes and the second power supply potential is set to be ground potential GND. The input signal potential has its logic amplitude limited, current flows through the diodes in its steady state, and, therefore, the logic amplitude of the signal potential Vout of output signal line becomes Vdd-Vf to Vf.

    摘要: Core circuitry is configured with a transistor formed of a gate oxide film of a thin film thickness, receiving a first power supply voltage to operate. Interface circuitry is configured with a transistor formed of a gate oxide film of a thick film thickness, receiving a second power supply voltage to operate. An appropriate voltage is supplied to the substrate of a P channel MOS transistor and an N channel MOS transistor which are output drivers, based on a mode select signal set according to the voltage level of the second power supply voltage, whereby a PNP parasitic bipolar transistor and an NPN parasitic bipolar transistor are driven at high speed. Although the interface circuitry of a semiconductor device is configured with a transistor formed of a thick gate oxide film, the speed will not be degraded even if the power supply voltage is set at a low voltage level.

    摘要: A precharge circuit and a bit line load circuit are provided to a read bit line pair. The bit line load circuit continuously supplies a prescribed current to a read bit line. When data is written to one of memory cells selected in common by one read word line, the level of each read bit line will not be lowered to the level of the ground potential by the bit line load circuit if a read word line is activated, and therefore the loads of both discharge and charge operations by transistors in the memory cell are reduced.

    摘要: An input circuit of an input-output device has a waveform shaping function to relieve waveform distortion at an input-output line so that the upper bound of an operating frequency is enhanced while keeping sufficiently high and low signal levels. A signal waveform given to the input-output line is shaped by an inverter and transmitted as an input signal to an internal circuit. When receiving a signal, the input circuit of the input-output device uses a feedforward operation on the signal applied to the input-output line so as to shape the signal present on the input-output line. A period for the feedforward operation is determined by the delay time of a delay element.

    摘要: To obtain a bus system capable of saving power consumption without increasing the number of data lines. In precharge period, by charging and discharging by data line drive circuits (23p, 23n), potentials of data lines (30, 31) of a bus (1) are set to power source potential (VDD) and grounding potential (GND), respectively. In equalizing period, by connecting the data lines (30, 31) by a switch (3), the potentials of the data lines (30, 31) are set to an intermediate potential of the power source potential (VDD) and grounding potential (GND). In data transfer period, by selectively connecting between data line (3) and power source line, and between data line (31) and grounding line, by means of data line drive circuits (23p, 23n), the signals transmitted through the data lines (30, 31) are caused to swing between the intermediate potential and power source potential (VDD), and between the intermediate potential and grounding potential (GND). A receiver circuit (25) converts the transmitted signal into a signal swinging between the power source potential (VDD) and grounding potential (GND).

    摘要: A semiconductor logic circuit apparatus includes a plurality of logic circuits each including complementary field effect transistors, and a plurality bipolar transistors associated with the respective ones of the logic circuits. When any one of the outputs of the logic circuits becomes high, an associated bipolar transistor becomes conductive to cause an output terminal of the apparatus to be charged from a voltage supply. With all the outputs of the logic circuits being low, all of the bipolar transistors are non-conductive, and a current supply coupled between the output terminal and ground dicharges charge on the output terminal.
