  • Publication number: 20080247258
    Abstract: A leakage current of the MOS transistor of a power control section at a standby time is drastically reduced and the reduction of the consumption power is achieved. A memory module is provided with power control sections. When either of the memory mats is not selected, the power control sections stop the power supply voltage to a non-selected memory mat, a word driver, an input-output circuit, a control circuit and an output circuit. At the standby time of the memory module, the power control section stops a power supply to power control sections, a control circuit, a predecoder circuit, and an input circuit. In this manner, the leakage current of the MOS transistor of the power control sections at the standby time can be drastically reduced.

  • Patent number: 6788561
    Abstract: To a first signal line to which a signal with a comparable small amplitude against the power supply voltage is transmitted at a first timing, a second signal line to which a voltage maintained at a constant is transmitted at the first timing is laid out on the same wiring layer as that of the first signal line adjacently to each other. Thereby, the invention reduces the coupling noises without impairing a high density of the signal wirings, and provides a semiconductor integrated circuit device with a memory circuit that realizes a high integration, low power consumption, and high speed.
