Abstract
A semiconductor integrated circuit device includes a first chip, a second chip to transmit and receive data to and from the first chip, and a through circuit provided in the first chip to transfer a clock signal and a test signal to the second chip. The clock signal and the test signal is inputted from an external device. The through circuit adjusts timing relation between the clock signal and the test signal based on a timing adjust signal. The timing adjust signal is inputted from the external device.
