    摘要: A semiconductor device and a computer system, incorporating the same, is capable of capturing an external signal at a high speed and stably operating independent of the duty ratio of a clock signal. An external signal ADD is captured into an address latch 22 by a level latch. The level latch is controlled to a through state at the timing in which the external signal is decided and controlled to a latched state in the decision period of the external signal. A pulse generation circuit controls the timing for switching a latch to the through state to a desired timing by a pulse generation circuit 30 in a chip. According to the above structure, the capture of the external signal ADD can be accelerated because the capture of the signal is determined by the setup timing. Moreover, because a latching period is controlled by the pulse generation circuit in the chip, operations are performed in a stable manner without having to depend upon the pulse width of an external clock CLK.

    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.
