  • Patent number: 8896033
    Abstract: The object of the invention is to provide a three-terminal switch (electrochemical transistor) capable of achieving sharp on-off operation. A source electrode and a drain electrode are juxtaposed with an insulator interposed between them, and on the assembly there is an ion diffusion member such as Ta2O5 located. On the opposite surface of the ion diffusion member, there is a gate electrode located that is capable of supplying metal ions such as copper ions. By application of voltage to the gate electrode, the metal ions going out of the gate electrode are reversibly precipitated as metal on both source and drain electrodes as well as on the insulator near them, thereby controlling conduction and non-conduction between the source electrode and the drain electrode.

    Abstract: There is a bi-level bit line architecture. Specifically, there is a DRAM memory cell and cell array that allows for six square feature area (6F2) cell sizes and avoids the signal to noise problems. Uniquely, the digit lines are designed to lie on top of each other like a double decker overpass road. Additionally, this design allows each digit line to be routed on both conductor layers, for equal lengths of the array, to provide balanced impedance. Now noise will appear as a common mode noise on both lines, and not as differential mode noise that would degrade the sensing operation. Furthermore, digit to digit coupling is nearly eliminated because of the twist design.

  • Patent number: 6365950
    Abstract: The present invention relates to a CMOS active pixel sensor which includes a compensation circuit capable of compensating a lowered pixel voltage output due to leakage current of a photodiode. The CMOS active pixel sensor having a light sensing unit for generating an output voltage when light is incident thereupon, the sensing unit having an amount of leakage current before the incidence of light. A reset unit resets the output voltage of the light sensing unit to an initial reset voltage in response to a reset signal. A sense transistor has a source, a drain coupled to a power source voltage, and a gate coupled to the output of the light sensing unit. A select transistor has a drain connected to a source of the sense transistor, and provides the voltage of the sense transistor to a bit line, in response to a select signal. A compensation unit supplies a voltage corresponding to the output voltage of the light sensing unit lowered by the leakage current.

  • Patent number: 5396527
    Abstract: A logic circuit is driven by a single alternating voltage power supply so that the energy stored in parasitic capacitances can be mostly recovered, rather than dissipated, as in conventional logic designs. Successive stages of the logic circuit are of opposite conductivity types such that the successive stages are activated in alternate half cycles of the power supply without separate clock signals. Each stage of the logic circuit is precharged during a respective first half cycle of the power supply and is active in logical processing during a second half cycle. The half cycles are defined by the rising and falling edges of the power supply. The logic circuit resonates with an inductor coupled across the power supply but closely coupled to the logic circuit. This inductor and the method of charging and discharging the capacitors in the logic circuit serve to minimize the power dissipated during logical processing.

  • Patent number: 5298771
    Abstract: A multi-color imaging charge-coupled array comprises a plurality of photosensitive layers, each sensitive to a specific range of wavelengths as would be found in a full-color image. The various photosensitive layers are separated by boundary layers of high band-gap energy, so that charge packets formed within individual layers are insulated from charge packets formed in other layers within the same pixel. The combination of photosensitive layers and high band-gap boundary layers cause charge packets to be formed in potential wells within each pixel area of the charge-coupled array.
