  • Publication number: 20180182588
    Abstract: A system includes a fuse pump; a fuse that can be blown by the fuse pump; and a voltage source configured to provide a first voltage only if the fuse pump is enabled to blow the fuse, the fuse pump blowing the fuse when the first voltage serves as a supply voltage of the fuse pump. If the first voltage serves as a supply voltage of the fuse pump, a first consumed time is required to blow the fuse. If a second voltage, provided by the voltage source, were to be served as a supply voltage of the fuse pump, a second consumed time is required to blow the fuse. The first consumed time is less than the second consumed time.
