Abstract: A resynchronization circuit possesses a sufficient migration margin even when the speed of a clock signal used for outputting data is increased, so that the data transfer speed can be increased. In the resynchronization circuit, a determination circuit holds a signal which is determined according to the phase difference between a determination signal and a reference clock signal (determination result). In a synchronization circuit block, a received data signal is held in synchronization with a strobe signal. Then, the received data signal is held in synchronization with a clock signal which has the same frequency as that of the reference clock signal and has a phase determined according to the determination result and output from the resynchronization circuit.

Abstract: A first semiconductor integrated circuit is connected to a second semiconductor integrated circuit with a cable. In the first semiconductor integrated circuit, when a power supply voltage becomes less than a set voltage detection level, a voltage-detecting circuit outputs a voltage-detected signal to lower the voltage of the cable and to stop the operation. The second semiconductor integrated circuit detects the decrease in the voltage of the cable to recognize the halt of the operation of the first semiconductor integrated circuit. In the first semiconductor integrated circuit thus configured, in testing the operation under low-voltage conditions in which the power supply voltage is less than the set voltage detection level, the voltage-detecting circuit receives a control signal from an external terminal to stop the operation forcibly.

Abstract: A terminal resistor built in a signal-sending or signal-receiving semiconductor integrated circuit is composed of a parallel circuit of a polysilicon resistor element having excellent frequency characteristic and a P-type MOS transistor. The resistance value of the polysilicon resistor element is set so as to be an approximate value of the characteristic impedance of a transmission line to be connected. The gate voltage of the P-type MOS transistor is controlled by a gate bias voltage adjustment circuit. The resistance value of the P-type MOS transistor is variably adjusted. Variation in the resistance value of the polysilicon resistor element due to dispersion in its manufacturing process is absorbed by variably adjusting the resistance value of the P-type MOS transistor. The combined resistance value of the polysilicon resistor element and the P-type MOS transistor is adjusted with high precision just to the characteristic impedance of the transmission line.
