Abstract

In a method of repairing through-electrodes, a plurality of through-electrodes are grouped into a plurality of through-electrode groups. A plurality of redundant through-electrodes are grouped into a plurality of redundant through-electrode groups. Repair paths for the plurality of through-electrodes are searched. When searching the repair paths, in response to a Y-th through-electrode included in an X-th through-electrode group being a defective through-electrode or in response to receiving a first signal from an (X−1)-th through-electrode group, it is determined whether a y-th redundant through-electrode included in an x-th redundant through-electrode group is available for performing signal transmission thereto. In response to the y-th redundant through-electrode being available for performing signal transmission thereto, a second signal input to the Y-th through-electrode is transmitted to the y-th redundant through-electrode. In response to the y-th redundant through-electrode being unavailable for performing signal transmission thereto, the second signal input to the Y-th through-electrode is transmitted to an (X+1)-th through-electrode group.
