Semiconductor device with signal lines and shield lines
摘要:
A semiconductor device may include, but is not limited to, a first signal line, a second signal line, and a first shield line. The first signal line is supplied with a first signal. The first signal is smaller in amplitude than a potential difference between a power potential and a reference potential. The second signal line is disposed in a first side of the first signal line. The second signal line is supplied with a second signal. The second signal is smaller in amplitude than the potential difference. The first shield line is disposed in a second side of the first signal line. The second side is opposite to the first side. The first shield line reduces a coupling noise that is applied to the first shield line from the second side.
