Abstract
An electrical fuse programming control circuit includes a plurality of fuse blocks each having a plurality of electrical fuses and an end fuse block. When all of the fuse blocks are programmed, the end fuse block is enabled and generates a programming control signal. The electrical fuse programming control circuit also includes a comparing unit that selectively transmits a fuse cutting signal to the plurality of fuse blocks in response to the programming control signal from the end fuse block. When programming of all of the fuse blocks is complete, reprogramming of the fuse blocks is not performed when an illegal program command is provided as an input.
