Abstract
The fuse device includes a plurality of fuse circuits, a global latch circuit and a plurality of local latch circuits. The global latch circuit is coupled to the fuse circuits. The global latch circuit is used to sense the blown states of the fuse circuits at different times, so as to output the fuse information of the fuse circuits at the different times. The local latch circuits are coupled to the global latch circuits. Each of these local latch circuits latches the fuse information output by the global latch circuit at the different times.
