摘要： An improved buffer circuit arrangement is provided which is particularly useful for semiconductor integrated circuit semiconductor memories and microprocessors. The buffer circuit is capable of switching large loads in various types of LSIs, and features a low noise and high speed circuit operation. This is accomplished by a parallel connection of output transistors in an output buffer circuit, and by differentiating the starting time of operation between the output transistors connected in parallel without using a delay circuit. For example, differentiating the starting times can be achieved by either providing the transistors with different characteristics from one another or the driving circuits with different characteristics from one another. Another aspect of the circuit is the provision of a two-level preset arrangement which presets the output node of the circuit to predetermined values before the input signals are applied.

摘要： A semiconductor integrated logic circuit is provided which includes a plurality of logic gates each having a first input terminal for respectively receiving first input signals, wherein each of the logic gates is 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. This arrangement is particularly effective for decoders in semiconductor memory circuits which use a common NMOS to receive one input for a plurality of logic decoder gates. An improved read/write arrangement is also provided for semiconductor memory circuits 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： An input buffer for processing an external signal is provided in one of passways, which is the most closest to a line for equally dividing the whole of a plurality of memory cell blocks longitudinally or laterally into two sections, the passway interposing between the adjacent memory cell blocks of the plurality of memory cell blocks to which a processed signal of the input buffer is transmitted, whereby the length of the signal pass from the input buffer to each memory cell of the memory cell blocks can be shortened. Therefore, since the memory cell or a logic element existing between the input buffer and the memory cell is operated by a pulse of little distortion without delay of time, a access time can be reduced and a processing speed of a microprocessor can be increased. Further, a degree of freedom in designing a system of a memory or the microprocessor is further improved.

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.
