  • Host device with power-saving function
    Patent number: 7975157
    Abstract: A card reader with power-saving function is used for being inserted with a memory card so that a computer can access the memory card through the card reader. When the memory card is inserted in the card reader, the card reader is enabled to operate. On the other hand, when the memory card is not inserted in the card reader, the card reader enters to a power-down mode for saving power.
    Type: Grant
    Filed: October 8, 2008
    Date of Patent: July 5, 2011
    Assignee: JMicron Technology Corp.
    Inventors: Lian-Chun Lee, Jian-Fan Wei, Kuen-Bin Lai, Chi-Tai Wu, Chien-Hui Chen

  • Look-up table methods for reducing the use of memory volume and system thereof
    Patent number: 7085792
    Abstract: The present invention relates to a look up table method for reducing the use of memory and more particularly to a condition while the input value has higher bits than the output value. This look up table method comprises: data storing that storing the input data into memory corresponding with output data with reference to the address of output data; and data searching including reading an input data, finding a closest address to the input data, and outputting the closest address. In this present invented look-up table method, the relation curve between the output value and corresponded input value is a monotonic curve, such as a ? curve.
