  • Patent number: 11079965
    Abstract: A data processing method for a computer system is provided. The computer system includes a host and an open-channel solid state drive. The open-channel solid state drive is connected with the host. The data processing method includes the following steps. Firstly, plural block characteristic parameters of a specified block in a non-volatile memory of the open-channel solid state drive are collected. Then, the plural block characteristic parameters are inputted into a prediction function, so that a prediction value is acquired. If the prediction value exceeds a threshold value, a data in the specified block of the non-volatile memory is moved to a blank block of the non-volatile memory by the host.

  • Patent number: 10642328
    Abstract: A solid state drive with a reset circuit includes a controlling circuit, a flash array and a buffer. The controlling circuit includes a physical layer circuit and a first input/output port. The first input/output port is connected with a first reset terminal of a host. The flash array and the buffer are connected with the controlling circuit. When the first reset terminal of the host activates a reset signal, a voltage level of the first input/output port is changed. After a delay time, the voltage level of a second reset terminal of the physical layer circuit is changed and the physical layer circuit is reset.

  • Patent number: 7990739
    Abstract: A resonant power converter is provided and includes a capacitor, an inductive device, a first transistor, a second transistor, and a control circuit. The capacitor and the inductive device develop a resonant tank. The first transistor and the second transistor are coupled to switch the resonant tank. The control circuit generates a first signal and a second signal to control the first transistor and the second transistor respectively. Frequencies of the first signal and the second signal are changed for regulating output of the resonant power converter. The control circuit is further coupled to detect an input voltage of the resonant power converter. A pulse width of the second signal is modulated in response to change of the input voltage.

  • Patent number: 7911813
    Abstract: A synchronous rectifying circuit of a resonant switching power converter is provided to improve the efficiency. The synchronous rectifying circuit includes a power transistor and a diode connected to a transformer and an output ground of the power converter for rectifying. A sense transistor is coupled to the power transistor for generating a mirror current correlated to a current of the power transistor. A controller generates a driving signal to control the power transistor in response to a switching-current signal. A current-sense device is coupled to the sense transistor for generating the switching-current signal in response to the mirror current. The controller enables the driving signal to turn on the power transistor once the diode is forwardly biased. The controller generates a reset signal to disable the driving signal and turn off the power transistor once the switching-current signal is lower than a threshold.

  • Publication number: 20070247512
    Abstract: In a track control method for marking a label side of an optical disc, a data side of the optical disc is first oriented to an optical head. A light beam is then emitted and a sled carrying the optical head moves. A series of moving distances of the sled are calculated according to the light beam reflected by the optical disc, which are then recorded in a memory. The optical disc is then flipped to have the label side face the optical head, and the shift of the optical head is controlled to mark on tracks of the label side according to the series of moving distances recorded in the memory.
