Abstract
The semiconductor integrated circuit according to the present invention comprises a plurality of receiving circuits each for receiving a plurality of input signals in synchronization with a timing signal. The input signals supplied to each of the receiving circuits are made equal in propagation delay times from their respective input terminals to the receiving circuit. Since the receiving circuits can receive the input signals of little skew, the timing margin required for the reception is minimized. That is, high speed operation becomes possible. At the same time, because the input signals corresponding to each individual receiving circuit are made equal in propagation delay time, the wiring for transmitting the input signals can be arranged in a minimum area. This can reduce the chip area, with reduction in chip costs.
