  • Resistive memory device having enhanced resist ratio and method of manufacturing same
    Patent number: 7579612
    Abstract: Disclosed herein are new resistive memory devices having one or more buffers layer surrounding a dielectric layer. By inserting one or more buffer layers around the dielectric layer of the device, the resistive ratio of the device is highly enhanced. For example, tests using this unique stack structure have revealed a resistance ratio of approximately 1000× over conventional electrode-dielectric-electrode stack structures found in resistive memory devices. This improvement in the resistance ratio of the resistive memory device is believed to be from the improved interface coherence, and thus smoother topography, between the buffer layer(s) and the dielectric layer.

  • COMMUNICATION SYSTEM AND OSCILLATION SIGNAL PROVISION METHOD
    Publication number: 20090201092
    Abstract: An embodiment of a communication system is provided, in which a high frequency oscillator generates a first high frequency signal upon receipt of no disable signal. The first high frequency signal is commonly shared by at least two modules. Each module coupled to the high frequency oscillator operates in either busy or idle mode, wherein the module operates at the first high frequency signal when in busy mode, and asserts a request signal when in idle mode. A disablement unit, coupled to the first and second modules, asserts the disable signal to the high frequency oscillator when all of the request signals are asserted, thereby forcing the high frequency oscillator to cease the generation of the first high frequency signal.
