  • Patent number: 7317632
    Abstract: A non-volatile memory storage device with functions of boosting supply voltage and signal level can adopt a non-volatile memory having an operating voltage higher than the supply voltage provided by the host device as a storage medium. The non-volatile memory storage device includes a supply voltage booster, a non-volatile memory storage unit and a controller. The supply voltage booster boosts the lower supply voltage provided by the host device up to the higher operating voltage of the non-volatile memory. The controller adjusts the interface signal to a proper interface signal level by cooperating with the supply voltage and the operating voltage so as to avoid the interface from damage owing to an over high signal level or avoid the non-volatile memory unit from not correctly receiving signal due to an over low signal level.

  • Patent number: 6880024
    Abstract: An application IC that can be applied in the control system of a memory storage device for the USB device for communicating with a server for receiving, reading and writing commands from the server and to access to the data stored in various memory storage devices is provided. Alternatively, the application IC can support the server, including IDE portable information product for data transmission. The data transmission having these two different specifications can share the same data source in certain mechanism. In this mechanism, the USB server is in the first priority transfer mode, the IDE server will take action only when the USB server is unavailable or discharged. When the IDE server is in operation mode, the interruption demand from the USB server is denied and after the IDE server completes the assignment, the interruption command from the USB server is executed.

  • Publication number: 20040240272
    Abstract: The personal digital device of the present invention comprises a flash memory that comprises one or more than one signal marks representing related preset parameter(s) or information for the player in the free space, the preset parameter(s) or information is, for example, music, volume, vision, playing sequence and so on. Thus when the user turns on the player, the controller within the player identifies and retrieves the signal mark stored in the free space of the flash memory, and retrieve the preset parameters or information previously stored or set as the signal mark, and therefore the player is capable of reproducing preset parameters or information. Thus, the inconvenience of setting, for example, sound, volume of the sound, vision and the like, each time the player is turned on can be effectively eliminated.
