Abstract:
A semiconductor memory device includes a plurality of repair fuse units configured to program repair target addresses respectively for repair target memory cells, wherein at least one of the repair fuse units is programmed with data information used for different purposes from the repair target addresses, a plurality of address comparison units each configured to compare an access target address with a corresponding address of the repair target addresses and determine whether to perform a repair operation or not, and a data transfer unit configured to transfer the data information to a corresponding circuit of the semiconductor memory device.
