Abstract:
A semiconductor device and a method for driving the same rapidly detect failure of a through-semiconductor-chip via and effectively repairing the failure using a latching unit assigned to each through-semiconductor-chip via. The semiconductor device includes a plurality of semiconductor chips that are stacked, and a plurality of through-semiconductor-chip vias to commonly transfer a signal to the plurality of semiconductor chips, wherein each of the semiconductor chips includes a multiplicity of latching units assigned to the through-semiconductor-chip vias and the multiplicity of latching units of each of the semiconductor chips constructs a boundary scan path including the plurality of through-semiconductor-chip vias to sequentially transfer test data.
