Abstract
A semiconductor integrated circuit device has a normal operation mode and a scan test operation mode, and includes a pulse generating circuit and a scan flip-flop circuit. The pulse generating circuit generates pulse signals synchronized with a clock signal in each of the normal and scan test operation modes. The scan flip-flop circuit latches data in response to the pulse signals from the pulse generating circuit signal in each of the normal and scan test operation modes.
