Circuit and device for fusing fuse wire

The embodiment of the invention discloses a circuit and device for fusing a fuse wire. The circuit for fusing a fuse wire includes a signal input unit, a trigger unit, a signal latch unit, a timing control unit and at least one fuse wire connection unit; through the signal input unit, control information is input into the trigger unit and the signal latch unit separately; the trigger unit generates fusing trigger signals according to the control information, and sends the fusing trigger signals to the signal latch unit; therefore, the signal latch unit generates first fusing signals accordingto the fusing trigger signals and the control information, and sends the first fusing signals to the timing control unit; the timing control unit generates second fusing signals according to the firstfusing signals and preset clock signals, and the fuse wire connection unit for connecting the fuse wire fuses the fuse wire according to the second fusing signals. The circuit and device for fusing afuse wire achieve that whe
