Abstract
In one embodiment, a protection circuit in a semiconductor device includes first and second transistors including gates electrically connected to a first node, and connected in series to each other between the first and second lines, third and fourth transistors including gates electrically connected to a second node between the first and second transistors, and connected in series to each other between the first and second lines, and a fifth transistor including a gate electrically connected to a third node between the third and fourth transistors, and provided between the second node and the second line. The protection circuit further includes an arithmetic circuit configured to perform calculation using a first signal received from the second node to output a second signal, and a sixth transistor configured to receive the second signal to output a control signal to the arithmetic circuit.
