5. A method of operating a multi-chip package including a plurality of semiconductor chips that are coupled with each other through normal through silicon vias and repair through silicon vias, the method comprising:
-
applying a test data to each of the normal through silicon vias and the repair through silicon vias; determining a number of normal through silicon vias that are failed, a number of normal through silicon vias that operate normally, a number of repair through silicon vias that are failed, and a number of repair through silicon vias that operate normally based on the test data; deciding whether to perform a repair operation based on the number of normal through silicon vias that are failed, the number of normal through silicon vias that operate normally, the number of repair through silicon vias that are failed, and the number of repair through silicon vias that operate normally to produce a decision result; and performing the repair operation based on the decision result. - View Dependent Claims (6, 7)
