Semiconductor integrated circuit

摘要

According to one embodiment, a semiconductor integrated circuit includes a clock signal transmission path configured to transmit a clock signal and a data transmission path configured to transmit data. The clock signal transmission path has a first and a second clock signal transmission line configured to transmit a clock signal and a complementary clock signal. The data transmission path has a first and a second data transmission line configured to transmit data and complementary data. Each transmission path has an amplifier circuit of each signal and a level adjustment circuit for reducing amplitude of output from the amplifier circuit.
