    • The present invention relates to a logic circuit consisting of an improved basic logic circuit which permits a wired logic operation and is suitable for constructing a large-scale integrated circuit (LSI). In most of the conventional basic logic circuits, because the output current is bi-directional, it is impossible to carry out the wire logic operation. In the improved basic logic circuit, since the output current is uni-directional, the only requirement is that the outputs of the plural basic logic circuits be connected with each other for carrying out the output wired-OR logic and the output wired-AND logic operations, so that the logic circuit is composed of a number of basic logic circuits, which number is smaller than the number of the conventional logic circuits. Accordingly, the following advantages can be obtained by utilizing the present invention: an improvement in the IC level of the semi-conductor IC device, a reduction in the cost of manufacturing the device and an increase in the operating speed of the device.
    • 本发明涉及一种由改进的基本逻辑电路组成的逻辑电路,该电路允许有线逻辑运算并且适用于构建大规模集成电路(LSI)。 在大多数传统的基本逻辑电路中,由于输出电流是双向的,所以不可能执行线逻辑运算。 在改进的基本逻辑电路中,由于输出电流是单向的,唯一的要求是多个基本逻辑电路的输出彼此连接,用于执行输出有线逻辑和输出有线和逻辑 操作,使得逻辑电路由多个基本逻辑电路组成,其数量小于常规逻辑电路的数量。 因此,通过利用本发明可以获得以下优点:半导体IC器件的IC电平的改善,器件制造成本的降低和器件的工作速度的提高。
