Semiconductor integrated circuit, latch circuit, and flip-flop circuit

A semiconductor integrated circuit connected between a first node and a second node, the semiconductor integrated circuit comprising:

• a first transistor of a first conductivity type located between a first potential node to which a first potential is applied and the first node, and having a gate connected to the second node;
• a second transistor of a second conductivity type having a drain connected to the first node;
• a third transistor of the second conductivity type located between a third node connected to a source of the second transistor and a second potential node to which a second potential is applied, and having a gate connected to the second node;
• a fourth transistor of the first conductivity type having a source and a drain either one of which is connected to a gate of the second transistor, and a gate and the drain to both of which the second potential is applied;
• a fifth transistor of the first conductivity type located between a drain of the first transistor and the first node;
• and
• a sixth transistor of the second conductivity type having a gate and a drain to both of which the first potential is applied, and a source connected to a gate of the fifth transistor,
• wherein when a signal at the second node changes, a third potential for turning on the fourth transistor is applied to the gate of the fourth transistor, and a potential obtained by shifting the third potential by a threshold of the fourth transistor is applied to the gate of the second transistor.
