Semiconductor integrated circuit device and low-amplitude signal receiving method

摘要

When signal transmission is performed between two semiconductor integrated circuit devices in synchronization with a clock signal using a small signal amplitude relative to an operating voltage of the two semiconductor integrated circuit devices, a received signal is held in the receiving semiconductor integrated circuit device in synchronization with the clock signal while the small signal amplitude of the held signal is kept substantially without change. The received signal having the small signal amplitude is amplified along a signal transmission path including a combined logic circuit to a subsequent latch circuit of the receiving semiconductor integrated circuit device.
