    摘要: In the present invention, an external power source supplied to an integrated circuit device is divided into a first external power source for the DLL circuit and a second external power source for circuits other than the DLL circuit. According to the present invention, it is arranged that power source noise generated in the second external power source cannot be transmitted to the variable delay circuit by utilizing the first external power source preferably for the variable delay circuit of the DLL circuit and even more preferably for its delay unit. Also, preferably, it is arranged that power source noise generated in the second external power source cannot be transmitted to the phase coincidence detection unit by utilizing the first power source for the phase coincidence detection unit in the phase comparison circuit of the DLL circuit. Also, by connecting the first external earthing power source to the variable delay circuit and/or phase coincidence detection unit, the effect of power source noise from the second external earthing power source originating from the operation of circuits other than these is suppressed.

    摘要: A semiconductor integrated circuit is adapted to make invalid an external clock, externally supplied to the semiconductor integrated circuit, when the semiconductor integrated circuit is set in an active power-down state. The semiconductor integrated circuit includes a delay locked loop DLL circuit which outputs an internal clock which phase is synchronized to the external clock. A latch circuit retains control signals in synchronism with the internal clock output by the DLL circuit. An internal circuit performs a predetermined process based on the control signals supplied from the latch circuit.
