    • A cascade sense amplifier includes section separated sense amplifiers, a cascade wiring and a main sense amplifier. The main sense amplifier has a capacitance regulation element provided at a base potential of input transistors constituting a data input end. The element is comprised of a metal oxide semiconductor (MOS) transistor for forming a capacitance corresponding to a potential V.sub.SS mainly forming a capacitance by the cascade wiring. A size of the element is determined in the manner that the base potential drop time of the transistors is equal to a potential drop time of the cascade wiring when a power source voltage V.sub.CC drops. Even though the power source voltage V.sub.CC drops, the transistors have no cut-off condition so as to prevent the read-out time from delaying. Especially, if the element is comprised of a MOS transistor, it is possible to use an extremely thin gate insulation layer as a dielectric, thereby suppressing an increase of a chip size.

    • Each optical repeater in an optical transmission system includes an optical amplifier, and a control circuit for controlling the optical transmission. Furthermore, each optical repeater transmits management information to the next optical repeater. The control circuit checks the status of the optical amplifier and obtains monitoring information. The control circuit generates management information in accordance with the monitoring information and the management information transmitted from the upstream side optical repeater. The management information is converted to an optical signal and transmitted to the next optical repeater. A receiving station receives the management information. The management information includes an ID code for an optical repeater which has failed and the status of the failure. Different categories of management information have priorities which can be changed by the receiving station, and thus the receiving station can detect the status of the optical transmission line easily and flexibly.

    • A semiconductor IC device includes a memory cell group; a pair of bit lines connected to the cell group; plural equalization transistors T.sub.R connected between the bit lines; address transition detectors ATD for detecting changes in address bits; and plural equalizing pulse generating circuits composed of plural logical gates, 15 to 22, respectively and provided for each equalization transistor to generate an equalizing pulse signal to each equalization transistor so that the levels of the two bit lines can be equalized with each other. Since signals outputted from the address transition detectors are synthesized, in particular at a node to which the equalizing pulse signal is applied, the number of logical gate stages to synthesize the detector output signals can be reduced and the wire lengths (e.g. wire capacitances) of the logical gates can be well balanced, thus improving the equalizing speed of the IC device.
    • 半导体IC器件包括存储单元组; 连接到单元组的一对位线; 连接在位线之间的多个均衡晶体管TR; 用于检测地址位变化的地址转换检测器ATD; 以及多个均衡脉冲发生电路,分别由多个逻辑门15至22组成,并为每个均衡晶体管提供均衡脉冲信号,以产生均衡脉冲信号给每个均衡晶体管,使两个位线的电平相互相等。 由于从地址转换检测器输出的信号被合成,特别是在施加了均衡脉冲信号的节点处,可以减少用于合成检测器输出信号的逻辑门级数,并且可以减少线长度(例如线电容) 逻辑门可以很好地平衡,从而提高了IC器件的均衡速度。
