  • Patent number: 8266470
    Abstract: A clock generating device, method thereof and a computer system using the same are provided. The clock generating device includes a PLL module and a tuning module. The PLL module receives a reference clock signal, and generates an output clock signal as a basic clock of a computer system according to a phase difference between a reference clock signal and a feedback signal. The PLL module includes a frequency divider adjusting an intrinsic frequency dividing ratio according to a control signal and performs a frequency dividing processing on the output clock signal to generate a feedback signal. The tuning module coupled with the PLL module generates the control signal according to a VID of a CPU and one of the feedback signal and the reference clock. Therefore, the operation frequency of the components serving the output clock signal as the basic frequency in the computer system can be synchronously tuned.

  • Patent number: 8183623
    Abstract: A dual node memory device and methods for fabricating the device are provided. In one embodiment the method comprises forming a layered structure with an insulator layer, a charge storage layer, a buffer layer, and a sacrificial layer on a semiconductor substrate. The layers are patterned to form two spaced apart stacks and an exposed substrate portion between the stacks. A gate insulator and a gate electrode are formed on the exposed substrate, and the sacrificial layer and buffer layer are removed. An additional insulator layer is deposited overlying the charge storage layer to form insulator-storage layer-insulator memory storage areas on each side of the gate electrode. Sidewall spacers are formed at the sidewalls of the gate electrode overlying the storage areas. Bit lines are formed in the substrate spaced apart from the gate electrode, and a word line is formed that contacts the gate electrode and the sidewall spacers.

  • Patent number: 7958383
    Abstract: A computer system has an adjustable data transmission rate between a CPU and a core logic chip thereof. In the computer system, the CPU has a power state adjustable in response to a power management control signal issued by the core logic chip. For adjusting data transmission rate between the CPU and the core logic chip, a change of an asserted time of the power management control signal from a first time period to a second time period is first determined to obtain an index value. The data transmission rate is increased or decreased according to the index value.
