  • Patent number: 7692230
    Abstract: Disclosed herein is an improved memory device wherein the area occupied by a conventional landing pad is significantly reduced to around 50% to 10% of the area occupied by conventional landing pads. This is accomplished by removing the landing pad from the cell structure, and instead forming a conductive via structure that provides the electrical connection from the memory stack or device in the structure to an under-metal layer. By forming only this via structure, rather than separate vias formed on either side of a landing pad, the overall width occupied by the connective via structure from the memory stack to an under-metal layer is substantially reduced, and thus the via structure and under-metal layer may be formed closer to the memory stack (or conductors associated with the stack) so as to reduce the overall width of the cell structure.

  • Patent number: 7692607
    Abstract: A method for adjusting an image on the basis of characteristics of a display system is provided. The image includes M horizontal lines. Each of the M horizontal lines respectively includes N pixels. Each pixel has an original gray level. A look-up table previously stores a plurality of conversion coefficients related to the characteristics of the display system. The method first calculates an ith loading according to the N original gray levels of the N pixels in the ith horizontal line. Based on the ith loading, an ith conversion coefficient corresponding to the ith loading is selected from the plurality of conversion coefficients in the look-up table. The method respectively multiplies the N original gray levels of the N pixels in the ith horizontal line by the ith conversion coefficient to generate N new gray levels for the N pixels in the ith horizontal line, whereby the image is adjusted.

  • Patent number: 7692475
    Abstract: A switch circuit is disclosed. The switch circuit comprises: a hysteresis buffer, an electric switch, a first discharge resistor, a second discharge resistor, a capacitor, a feedback resistor, a first reciprocal switch, and a second reciprocal switch. When the second reciprocal switch is turned on, a power supply voltage charges the capacitor, and thus the voltage on the signal input terminal of the hysteresis buffer is decreased. Accordingly, the voltage on the signal output terminal of the hysteresis buffer is decreased, so as to turn on the electric switch. When the first reciprocal switch is turned on, the capacitor is discharged, and thus the voltage on the signal input terminal of the hysteresis buffer is increased. Accordingly, the voltage applied to the signal output terminal of the hysteresis buffer is increased, so as to turn off the electric switch.

  • Patent number: 7693022
    Abstract: A method for controlling read power and an open-loop read control device using the same. The open-loop read control device is used in an optical disk writer and includes a memory, a DAC and an amplifier. The optical disk writer includes a pickup head device having a laser diode. When writing is disabled, the read power of the optical disk writer for reading the disk corresponds to a specific voltage. The memory stores a relationship curve and outputs a corresponding reference value corresponding to the specific voltage. The DAC converts the corresponding reference value into an analog corresponding reference value. The amplifier receives the analog corresponding reference value and outputs a read power control voltage, which controls the laser diode to generate a substantially constant read power in the write process.

  • Publication number: 20100080298
    Abstract: A weighting function (WF) is previously provided to model the number of search points of a pattern search. However, WF fails to properly describe the behavior of the genetic pattern search algorithms due to some over-simplifications in their models. Therefore, a refined weighting function (RWF) is provided to more accurately describe both genetic and non-genetic pattern searches. Moreover, based on the understanding to RWF, two momentum-directed genetic search algorithms are further provided. These new algorithms check the possible mutations according to their likelihood to the preceding successful mutations and further accelerate the previous genetic pattern searches.
