    Abstract: A logic circuit to be formed in a gate array is selected depending upon the value of the output load capacitance thereof, from among a CMOS circuit, a first Bi-CMOS circuit including an output bipolar transistor whose emitter size is set at a predetermined value, and a second Bi-CMOS circuit including an output bipolar transistor whose emitter size is larger than the emitter size of the output bipolar transistor of the first Bi-CMOS circuit. That is, the logic circuit is brought into a circuit form whose output load capacitance can be charged and discharged fastest. As a result, the logic circuit constructed in the gate array by adopting such a design technique has its operating speed raised. An improved structure is also provided for reducing wiring lengths by arranging bipolar transistors in adjacent basic cells to have mirror symmetry with one another. Further, particular gate width relationships are provided between MOSFETs within basic cells for reducing propagation delay and the required occupation area.

    Abstract: A semiconductor memory device is provided which includes a plurality of memory arrays each including main word lines, sub word lines to which a plurality of memory cells are connected, and a decoder which selectively connects the sub word lines to the main word lines. The main word lines are relatively short, since they are isolated electrically between memory arrays, and their resistance can thus be relatively low. The main word lines are not directly connected with a plurality of memory cells, and this results in a smaller capacitance coupled to the main word lines than is customarily the case. Consequently, the semiconductor memory device can have an enhanced operating speed.

    Abstract: A semiconductor memory device includes an input circuit and an output circuit. To prevent the erroneous operation of the input circuit by the noise which develops at the time of the change of the output signal of the output circuit, the threshold voltage of the input circuit is changed, or an internal signal generated by the internal circuit is fixed to a predetermined level. In an output circuit having a tri-state output function, the threshold voltage of the input circuit is changed when the output is brought into the high impedance state, or the internal signal generated by the input circuit is fixed to a predetermined state. Using these arrangements it is possible to prevent the erroneous operation of the input circuit by the noise occurring when the output is brought into the high impedance state. Furthermore, in an output circuit having a tri-state output function, the threshold voltage of the input circuit is changed when the output signal of the output circuit is brought into the high impedance state, too, when the output signal changes. This makes it possible to prevent an erroneous detection of the level of the input signal which might otherwise be caused by the noise.

    Abstract: A semiconductor memory device wherein the equivalent series resistances that are interposed in series in the pairs of complementary data lines D, D, are substantially the same as one another among the individual complementary data lines D, D. The equivalent series resistance is comprised of pull-up MISFET's and column switching MISFET's that exist between the power source V.sub.CC and the sense circuit. Parity is maintained for the pull-up MISFET's (Q.sub.p, Q.sub.p) and the column switching MISFET's (Q.sub.y, Q.sub.y) that exist on the pairs of complementary data lines D, D. To maintain this parity, the two MISFET's are formed to have the same shape. In addition, the arrangement of contacts to the transistors are set so that the directions in which the currents flow and lengths of current paths are also the same. In other words, contact portions between aluminum electrode and source and drain regions are formed at the same positions in the two MISFET's.

    Abstract: A semiconductor integrated circuit device is provided for permitting operation of a CMOS or BiCMOS memory with ECL level input signals, in which operating speed is increased and power consumption is reduced.Input signals of ECL levels are received by an input buffer for amplifying the input signals to an output signal level within a range where differential transistors of the input buffer operate in an unsaturation region. The output signal of the input buffer is supplied to a CMOS circuit or Bi-CMOS circuit which is operated by both an operating voltage having a first-stage smaller absolute value than that of the operating voltage of the input buffer and the ground potential of the circuit. This first stage CMOS or BiCMOS circuit also includes an arrangement to further amplify the received signals to provide further level conversion.Since both the input buffer and the first-stage CMOS or Bi-CMOS circuit perform signal transmission and level conversions, high-speed operation and low power consumption can be achieved by a simple structure.
