    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: 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.
