Abstract:
A fuse monitoring circuit for a semiconductor memory device includes a fuse repair unit including a plurality of fuses each programmed with at least one repair address, configured to receive a fuse reset signal and to output a plurality of fuse state signals each corresponding to a connection state of one of the fuses, a fuse monitoring unit configured to receive a monitoring enable signal and to output a plurality of fuse state monitoring signals each corresponding to a corresponding one of the fuse state signals, each of the fuse state signals corresponding to one of a plurality of addresses, and an output unit configured to receive an output control signal and to output the fuse state monitoring signals to an output pad.
