Claim:
1. A smart self-repair device comprising: a fuse array configured to store information regarding respective bits of a fail address in fuses; a self-repair control circuit configured to control repairing of not only a target mat in which a fail occurs, but also adjacent upper and lower mats sharing a sense amplifier along with the target mat, and to output fail address information corresponding to a fail mode, and row fuse set information or a column fuse set information; a data control circuit configured to output repair information to the fuse array based on the fail address information and the row fuse set information or the column fuse set information; a control circuit configured to control a rupture operation of the fuse array; and an oscillation circuit configured to output a clock signal to the self-repair control circuit based on a boot-up enable signal and a rupture enable signal.
