Abstract
A semiconductor chip includes a command address input circuit configured to generate a rising command address and a falling command address by receiving an external command address and configured to output the rising command address and the falling command address to a through electrode, and a test circuit configured to generate a detection signal by latching a remaining one of the rising command address and the falling command address as any one of the rising command address and the falling command address and configured to detect a fail in the transmission of the rising command address and the falling command address by detecting the logic level of the detection signal.
