    摘要： There is provided a method of controlling an internal address signal of an RAM in which a late-write method is realized on a chip. Two sets of address registers for reading and writing are provided for each address and further a middle register is provided between the two sets of address registers. The middle register is controlled by a signal formed by obtaining the AND result of a clock signal and a write enable signal and the two sets of address registers for reading and writing are controlled only by the clock signal. A selection circuit selects outputs of the two sets of address registers as an input in accordance with the write enable signal to control an internal address.

    摘要： A semiconductor integrated circuit device is divided into a plurality of blocks, which are individually equipped with signal generate units such that the signal generate units are distributed in the semiconductor integrated circuit device. The semiconductor integrated circuit device is preferably constructed to generate the pulse signal by the pulse generate units which are provided for the individual blocks, after all initial logic operations on the data and control signals have been taken. Thanks to this construction, an SRAM, for example, can have its write recovery time minimized to 0 so that it can achieve high-speed operations. Moreover, since predecoders are provided for the individual blocks, the wiring line number and area in the chip can be reduced to improve the degree of integration of the semiconductor integrated circuit device. Still moreover, signal delay and skew can be reduced in the chip so that high-speed can be achieved. Another feature is that either the input/output pads of the data into or out of the semiconductor integrated circuit device or their accompanying circuit units are distributed in the semiconductor integrated circuit device. The individual features described above can be used solely or in combination, if necessary, to achieve the above-specified objects.

    摘要： A static RAM includes pre-amplifiers, which are made up solely of emitter-follower transistors having their collectors supplied with the power voltage, in one-to-one correspondence to sub common data line pairs which are connected by column switches to complementary data line pairs of memory arrays. The pre-amplifier is provided with a first switch which turns on during the selected state to connect the sub common data line pair to the bases of the transistors and a second switch which turns on during the unselected state to provide the bases with a certain bias voltage lower than the readout signal voltage on the sub common data line pair. The emitter-follower transistors have their emitters connected commonly to form common emitter lines, which are connected to pairs of input terminals of main amplifiers made up of CMOS transistors.

    摘要： An arrangement which is particularly effective for decoders in semiconductor memory circuits which use, for example, common NMOS to receive one input for a plurality of logic decoder gates is provided includes a plurality of logic gates each having a first input terminal for respectively receiving first input signals and each being coupled to a common node. In one embodiment, first and second switching elements are also coupled to the common node. The first and second switching elements are both coupled to a second input terminal for receiving a second input signal which is common to the plurality of logic gates, and both operate complementary to one another in response to the second input signal. An improved read/write arrangement is also provided for such semiconductor memory circuit which includes circuitry to prevent connection of a common read line to the data lines during the writing operation. This enhances the writing speed by removing the load of the common read line during writing.

    摘要： A multiplex circuit is disclosed in which a plurality of bipolar transistors are combined and in which the respective base terminals thereof are used as inputs, thereby to construct an emitter follower type multiplex circuit. In such an emitter follower type multiplex circuit, the multiplexing function of non-selection/selection is effected by controlling the base potential of the respective bipolar transistors by providing a MOS transistor between each base and a high potential of the power source through a resistor and a current drawing circuit. In accordance with such a scheme, when a selection of one input signal is made, the bipolar transistor corresponding thereto is permitted to turn ON on the basis of an input signal supplied to the base terminal thereof. The bipolar transistors corresponding to the non-selection input signals are maintained OFF, through activating the current drawing circuits associated therewith, irrespective of the potential levels of the incoming input signals supplied to the base terminals thereof. In the emitter follower type multiplex circuit, a constant current source is also provided between the commonly connected emitters of the bipolar transistors and the power source of low potential. The multiplex arrangement effected can be of the collector dot type multiplex circuit. Such multiplex circuits are used with a semiconductor integrated circuit such as a memory circuit.
