  • SIGNAL GENERATING CIRCUIT AND RELATED STORAGE APPARATUS
    Publication number: 20110110173
    Abstract: A signal generating circuit is employed for generating a control in order to control operations of one of a controller and at least a storage unit of a related storage apparatus controlled by the controller. The signal generating circuit includes a voltage inputting unit and a voltage detection unit. The voltage detection unit rapidly switches a voltage level of the control signal according to a voltage to be detected which is generated by the voltage inputting unit. As a result, data damage due to unexpected operations performed by the controller during the power-off period can be avoided.
