  • Patent number: 8085104
    Abstract: An oscillation circuit, a driving circuit thereof, and a driving method thereof are provided. The driving circuit generates a second enable signal according to an output signal of an oscillator and a first enable signal. The second enable signal is transmitted to the oscillator. When a number of waves of the output signal within a predetermined period is smaller than a predetermined value, the driving circuit adjusts a voltage level of the second enable signal. A voltage level of the first enable signal is equal to an enable voltage level. Through variations in voltage levels of the second enable signal, the oscillator is triggered to oscillate.

  • Publication number: 20110067118
    Abstract: A method and a system for protecting data, a storage device, and a storage device controller are provided. In the present method, when a host accesses data in the storage device, whether the host performs a play operation or a copy operation on the data is first determined. If the host performs the play operation on the data, the storage device continues to execute the play operation so as to allow the host to access the data. On the other hand, if the host performs the copy operation on the data, the storage device executes an interference procedure so as to prevent or retard the data from being copied into the host.

  • Publication number: 20100264999
    Abstract: An oscillation circuit, a driving circuit thereof, and a driving method thereof are provided. The driving circuit generates a second enable signal according to an output signal of an oscillator and a first enable signal. The second enable signal is transmitted to the oscillator. When a wave number of the output signal is smaller than a predetermined value during a predetermined period, the driving circuit adjusts a voltage level of the second enable signal. A voltage level of the first enable signal is equal to an enable voltage level. Through variations in voltage levels of the second enable signal, the oscillator is triggered to oscillate.

  • Publication number: 20100252931
    Abstract: A flash memory storage apparatus is provided. The flash memory storage apparatus includes a substrate, a control and storage circuit unit, a ground lead, at least a signal lead, and a power lead. The control and storage circuit unit, the power lead, the signal lead, and the ground lead are disposed on the substrate, in which the power lead, the signal lead, and the ground lead respectively electrically connect to the control and storage circuit unit. Moreover, the flash memory storage apparatus further includes an extra ground lead electrically connected to the ground lead or a protrusion on the substrate, such that the ground lead first electrically connects to a host when the flash memory storage apparatus is plugged into the host.
