  • Patent number: 10418086
    Abstract: A volatile memory storage apparatus including a memory array, a refresh circuit and a pre-programmed circuit is provided. The memory array includes a plurality of memory banks. The refresh circuit is coupled to the memory array. The refresh circuit is configured to refresh the memory banks according to different refresh frequencies. The pre-programmed circuit is coupled to the refresh circuit. The pre-programmed circuit is configured to store the refresh frequencies. In addition, a refresh method of a volatile memory storage apparatus is also provided.

  • Patent number: 9785344
    Abstract: A portable electronic apparatus and a touch detecting method thereof are provided. In the method, a touch is detected by a touch screen of the portable electronic apparatus. Then, whether the touch is located in an edge area of the touch screen is determined. If it is determined that the touch is located in the edge area of the touch screen, the touch time during which the touch continues and no other touch is detected by the touch screen is accumulated, and whether the accumulated touch time exceeds a preset time is determined. If the accumulated touch time exceeds the preset time, related information of the touch is removed from an event triggered by the touch until the touch ends.

  • Patent number: 9256278
    Abstract: A power management device is adopted in a memory device which includes a first memory unit and a second memory unit, including a first voltage regulator, a second voltage regulator, and a controller. The first voltage regulator receives a supply voltage from an external supply source and provides a first internal voltage to the first memory unit. The second voltage regulator receives the supply voltage from the external supply source and provides a second internal voltage to the second memory unit. The controller independently enables or disables the first voltage regulator and the second voltage regulator according to a control signal.

  • Patent number: 8947960
    Abstract: A storage medium including a plurality of memory cells, a plurality of transmission lines, a driving module and a floating detection module is disclosed. The memory cells store data. The transmission lines are coupled to the memory cells. The driving module accesses the memory cells via the transmission lines. The floating detection module includes a reset unit, a plurality of connectors and a detector. The reset unit is coupled to a detection line. Each of the connectors is coupled between one of the transmission lines and the detection line. The detector determines whether a state of at least one of the transmission lines is a floating state according to a level of the detection line.
