  • Patent number: 9009571
    Abstract: A storage medium receiving write data provided by a host device, providing read data to the host and including a first module and a second module is disclosed. The first module includes a first memory cell and a first controller. The first memory cell stores the write data. The first controller reads the first memory cell to generate a first accessing result. The second module includes a second memory cell and a second controller. The second memory cell stores the write data. The second controller reads the second memory cell. When the first accessing result has an error and the error cannot be corrected by the first controller, the first controller requests the second controller to read the second memory cell to generate a second accessing result, and the second controller serves the second accessing result as the read data and provides the read data to the host.

  • Publication number: 20150076766
    Abstract: A magic cube structure includes a central core, a plurality of central blocks, a plurality of resettling devices, a plurality of elastomers, a plurality of side blocks and a plurality of corner blocks. Whereby, when one central block is rotated relative to the central core by an outer force, one central block is pressed by the corresponding resettling device and is axially moved away therefrom. Simultaneously, the recovery force of the corresponding elastomer is increased, so that a torque imposed on the central block is created; when the rotation operation is completed, the torque makes the central block fitly abutted against the corresponding resettling device. As a result, the recovery force returns to former state.

  • Publication number: 20140251422
    Abstract: A solar cell with doping blocks is provided, which includes: a semiconductor substrate, an anti-reflection layer, a plurality of front electrodes, and a back electrode layer. The semiconductor substrate has a first surface, and a plurality of doping block layers is arranged under the first surface and spaced from each other. The anti-reflection layer is disposed on the doping block layer and the semiconductor substrate. The front electrodes penetrate the anti-reflection layer and are arranged on the doping block layers. The back electrode layer is disposed on a second surface of the semiconductor substrate.

  • Publication number: 20130276130
    Abstract: A Secure Digital (SD) card, and an operating system and an operating method for the SD card are disclosed. The disclosed SD card has a Flash memory and a controller. The Flash memory contains a data storage space and a Content Protection Recorded Media (CPRM) support space. The controller executes a firmware of the SD card, such that read/write commands provided from a host for the CPRM support space are regarded and executed as security commands and a CPRM mechanism is operated over the data storage space.

  • Patent number: 8400140
    Abstract: A sensor system for receiving an input signal and applying a digital control signal to adjust an output sensitivity of a triggering signal within the sensor system. The input signal includes a bias DC and a fluctuation bias voltage. The sensor system includes a first voltage contact, a normalized voltage contact, a normalized circuit and a comparison circuit. The first voltage contact provides a first comparison voltage based on the digital control signal, wherein the first comparison voltage defines a standby voltage region. The normalized voltage contact provides a reference voltage based on the digital control signal, wherein the reference voltage is located within the standby voltage region. When the fluctuation bias voltage is located outside of the standby voltage region, the sensor system outputs a triggering signal so as to adjust the digital control signal.

  • Publication number: 20070215479
    Abstract: A method for monitoring the filling performance of a copper plating formula for microvia filling includes measuring a first potential value at a first rotation speed and a second potential value at a second rotation speed with a Cu-RDE of a plating solution. Then, a potential difference is obtained by subtracting the potential measured at the second rotation speed from the first rotation speed. The filling performance is defined by the potential difference; that is, a high potential difference indicates a good filling performance.
