  • Portable electronic device
    Patent number: 8508925
    Abstract: A portable electronic device includes a first body, a second body and a linkage. The first body has a first upper surface, and the second body has a second upper surface. An end of the linkage is coupled to the first body through a first pivot shaft and another end of the linkage is coupled to the second body through a second pivot shaft, in which the second body is suitable to be stacked on the first upper surface of the first body to make the portable electronic device in a retracted state. The linkage is suitable to rotate relatively to the first body so that the first body and the second body of the portable electronic device are side by side in an expanded state.
    Type: Grant

  • Method for copying data in non-volatile memory system
    Publication number: 20090106513
    Abstract: A method for copying data in a non-volatile memory system is disclosed. The method includes calculating a number of errors of a first set of data from a source block of the non-volatile memory saved in the buffer of the controller, transmitting the first set of data saved in the buffer of the controller to a buffer of the non-volatile memory when the number of errors is lower than a threshold, and programming a destination block of the non-volatile memory with the first set of data saved in the buffer of the non-volatile memory when the number of errors is lower than the threshold.

  • Flash memory system with higher data transmission rate and method thereof
    Publication number: 20080183948
    Abstract: A flash memory system is disclosed. The flash memory system includes a host and a flash memory card. The data transmission between the host and the flash memory card can be achieved with a clock signal for synchronization. The data is transmitted between the host and the flash memory card both at the falling edges and the rising edges of the clock signal.
