Semiconductor device

摘要

A method for bypassing a defective through silicon via x in a group of n adjacent through silicon vias, includes receiving a plurality of relief signals to identify the defective through silicon via x, activating x−1 switch circuits to connect x−1 data circuits to through silicon vias 1 to x−1 in the group of n adjacent through silicon vias, activating n−x switch circuits to connect n−x data circuits to through silicon vias x+1 to n in the group of n adjacent through silicon vias, and activating a switch circuit to connect a data circuit to an auxiliary through silicon via which is adjacent through silicon via n in the group of n adjacent through silicon vias.
