Semiconductor device

A semiconductor device comprising:

• a plurality of n data circuits;
• a plurality of n adjacent through silicon vias;
• an auxiliary through silicon via;
• a relief information circuit configured to provide a plurality of relief signals to identify a defective through silicon via x in the plurality of n through silicon vias, wherein x is an integer greater than 1 and n is an integer greater than x;
• and
• a plurality of n switch circuits, the plurality of n switch circuits being configured so that x−1 switch circuits of the n switch circuits are activated based on the relief signals to connect x−1 data circuits to through silicon vias 1 to x−1 in the plurality of n adjacent through silicon vias, n−x switch circuits of the n switch circuits are activated based on the relief signals to connect n−x data circuits to through silicon vias x+1 to n in the plurality of n adjacent through silicon vias, and a switch circuit of the n switch circuits is activated based on the relief signals to connect a data circuit to the auxiliary through silicon via;
• wherein each of the n switch circuits is configured to receive a data signal from a corresponding one of the n data circuits and to output the data signal to one of two through silicon vias of the n adjacent through silicon vias and the auxiliary through silicon via depending on the relief signals.
