Abstract

A semiconductor memory device includes a first fuse set block including a fuse array for storing first repair information, and a control block configured to store second repair information in a first mode, and generate an output control signal when input addresses applied from an external source and the second repair information are the same, in a second mode, wherein the first fuse set block enables a first match signal for accessing a first redundancy memory cell when the stored first repair information and the input addresses are the same, and disables the first match signal in response to the output control signal.
