    摘要: A noise suppression circuit encompasses an internal circuit, a bypass capacitor, first and second transistors. The internal circuit has high and low level terminals, and the low level terminal is connected to a low level power supply line. The internal circuit is supplied with enable and inverted enable signals. The first transistor has a first control electrode, and one main electrode is connected to the high level terminal. The first control electrode is supplied with the inverted enable signal. The bypass capacitor is connected between the other main electrode of the first transistor and the low level power supply line.

    摘要: A circuit is constructed on transistor level out of a net list and it is determined if the output node of a circuit for receiving a clock signal can go to a high impedance state from this circuit. If the output node can go to a high impedance state, it is designated as the starting point for a path searching operation and an input node of the circuit not receiving a clock signal is designated as the terminating point of the path searching operation. If, on the other hand, the output node cannot go to a high impedance state, the output node is designated as the clock node and an input node of the circuit not receiving a clock signal is designated as the terminating point of the path searching operation. With this arrangement, a sequential circuit can be divided into combinational circuits for certain.

    摘要: An internal row address signal output from an address buffer is supplied to first and second row partial decoders. A programming circuit is programmed to store information indicating whether the redundant function is used or not and a defective address corresponding to a defective main word line or defective memory cell in a main memory cell array. The defective row address and the internal row adders signal are compared with each other by the programming circuit and the spare decoder, a control signal corresponding to the coincidence/non-coincidence of the compared row addresses is output, and a partial decode signal of the internal row address signal is output when the compared row addresses coincide with each other. The second partial decoder receives a control signal output from the spare decoder and outputs a partial decode signal of the internal row address signal when the control signal indicates the non-coincidence of the compared row addresses. The partial decode signals output from the first and second row partial decoders are supplied to the main row decoder which in turn selects one of main word lines in the main memory cell array. The partial decode signal output from the spare decoder is supplied to a spare row decoder which in turn selects one of spare word lines in a spare memory cell array.
