Abstract

A fault-tolerant unit and a fault-tolerant method for through-silicon via (TSV) are provided. The fault-tolerant unit includes TSV structures TSV˜TSVn, nodes N˜N, nodes N˜Nand a switching module. The TSV structure TSVi is connected between the node Nof the first chip and the node Nof the second chip, wherein 1≦i≦n. The switching module is connected between the nodes N˜Nof the second chip and a test path of the second chip. In normal operation state, the switching module disconnects the test path and the nodes N˜Nwhen the TSV structures TSV˜TSVn are valid. The switching module connects the node Nto at least another one of the nodes N˜Nwhen the TSV structure TSVi is faulty in the normal operation state. In test status, the switching module connects the test path to the nodes N˜N.
