    摘要: Nonvolatile memory devices including device isolation patterns on a semiconductor substrate are provided. The device isolation patterns define a cell active region and a peripheral active region of the semiconductor substrate. Cell gate electrodes are provided that cross over the cell active regions. Memory cell patterns are provided between the cell gate electrodes and the cell active regions and extend toward the device isolation patterns. A tunnel insulation film is provided between the memory cell pattern and the cell active region. Related methods of fabricating nonvolatile memory devices are also provided herein.

    摘要: A nonvolatile memory device and method of making the same are provided. Memory cells may be provided in a cell area wherein each memory cell has an insulative structure including a tunnel insulating layer, a floating trap layer and a blocking layer, and a conductive structure including an energy barrier layer, a barrier metal layer and a low resistance gate electrode. A material having a lower resistivity may be used as the gate electrode so as to avoid problems associated with increased resistance and to allow the gate electrode to be made relatively thin. The memory device may further include transistors in the peripheral area, which may have a gate dielectric layer, a lower gate electrode of poly-silicon and an upper gate electrode made of metal silicide, allowing an improved interface with the lower gate electrode without diffusion or reaction while providing a lower resistance.

    摘要: A charge pump generates a first sub up current and a second sub up current that vary complementarily with a change in a voltage at an output terminal. The charge pump also generates a first sub down current and a second sub down current that vary complementarily with the change in the voltage at the output terminal. With such complementary relationships, the total up/down currents remain substantially constant and balanced with the change in the voltage at the output terminal.

    摘要: A voltage-controlled oscillator includes a bias circuit and a delay circuit. The bias circuit may generate a bias voltage signal pair having levels that are based on the voltage level of an input voltage signal and that are constrained by the values of a maximum current signal and a minimum current signal that are generated in the bias circuit. The delay circuit generates an output signal having a frequency that varies in response to the bias voltage signal pair. Because an operating frequency range of a voltage-controlled oscillator VCO is limited by a bias circuit, the VCO can operate with reduced gain and can limit the maximum operating frequency to a predetermined level. The VCO may also include a PTAT current generator in the bias circuit which can allow the VCO to compensate for variations of the VCO output frequency based on temperature.
