  • Patent number: 7848150
    Abstract: A flash memory device and a method of operating the same is disclosed, in which the conditions of voltage (or current) applied during the reading operation are differently adjusted according to an accumulated number of times of a programming operation, an erasing operation or a reading operation (an accumulated number of operation cycle). Even if a level of the threshold voltage is changed to a level which differs from that of the target voltage by an increase of the accumulated number of operation cycle regardless of the programming operation (or the erasing operation) being normally performed, the reliability of the reading operation can be enhanced to prevent a malfunction of the memory cell from being generated.

  • Publication number: 20100235105
    Abstract: A method to be implemented on or in a computer is disclosed, where the method includes data collection, calibration, candidate selection, and analysis of data streams associated with each candidate to classify single molecule fluorescence resonance energy transfer events. Once classified, the classification can be related to the nature of the events, such as the identification of dNTP incorporation during primer extension to obtain a base read out of an unknown template.

  • Patent number: 7785827
    Abstract: A method and composition for tRNA synthetases that activate and aminoacylate nonstandard and noncognate amino acids to tRNA adaptor molecules is described that can be used to generate custom designed protein products for uses in medicinal, therapeutic, diagnostic, biotechnology, engineering, and spectroscopy applications. Some tRNA synthetases naturally misactivate and misaminoacylate noncognate amino acids. Many of these tRNA synthetases, including but not limited to leucyl-, isoleucyl-, and valyl-tRNA synthetases, have evolved proofreading and editing mechanisms to correct these mistakes. Inactivation of the enzyme's editing activity allows and facilitates production and accumulation of tRNAs that are misaminoacylated with nonstandard and noncognate amino acids. These misaminoacylated tRNAs can be used to introduce novel amino acids into proteins.

  • Patent number: 7696577
    Abstract: A memory cell array in a semiconductor device includes a semiconductor substrate having active areas and isolation areas in parallel, a plurality of select lines having generally a U like shape and is configured to cross over the active areas and the isolation areas, and a plurality of word lines formed between the select lines. In view of the select line being formed in U like shape, an occurrence of a punch through phenomenon is prevented by a junction area formed between the select lines. As a result, a margin for reducing a width of the select line is increased.

  • Publication number: 20100045645
    Abstract: A backlight assembly has a lamp driving device for driving external electrode fluorescent lamps (EEFLs) parallel connected each other. The lamp driving device includes a power switch transistor, a diode, an inverter and a PWM controller. The transistor converts external DC power signal into pulse power signal based on switching signal, the diode prevents rush current from flowing into the transistor. The inverter converts the pulse power signal into AC power signal, raises voltage level of the AC power signal, and provides the lamps with the raised AC power signal. The PWM controller is activated by external on/off signal to provide the transistor with the switching signal so as to regulate voltage level of the AC power signal. The EEFLs can maintain a constant current level, and the backlight assembly can have characteristics of uniform luminance, high luminance and high heat efficiency.
