Abstract:
A semiconductor integrated circuit includes: a normal fuse cell array programmed with a normal fuse data; a dummy fuse cell array programmed with a verifying fuse data; and a sensor configured to read the verifying fuse data from the dummy fuse cell array and read the normal fuse data from the normal fuse cell array, wherein the normal fuse cell array is configured to be read according to a reading result of the dummy fuse cell array.
