Abstract:
A semiconductor memory device includes a first transistor including a first end connected to a first pad and a second end connected to a first node, a second transistor including a first end connected to a second pad and a second end connected to the first node, a third transistor including a first end connected to the second pad, a second end connected to the first node, and a gate connected to a second node and having a size different from that of the second transistor, a fourth transistor including a first end connected to the first pad, a second end connected to the second node, and a gate connected to the first node, and a fifth transistor including a first end connected to the second pad, a second end connected to the second node, and a gate connected to the first node.

Claim (Index 13):
A method of protecting a semiconductor memory device against a voltage surge at a first pad by turning on a power supply protection transistor connected between the first pad and a second pad while turning off the power supply protection transistor when there is no voltage surge at the first pad, said method comprising:\n in response to a voltage at the first pad exceeding a threshold voltage, pulling up a gate voltage of the power supply protection transistor to turn on the power supply protection transistor and cause a current to flow from the first pad to the second pad; and in response to the voltage at the first pad not exceeding the threshold voltage, pulling down the gate voltage of the power supply protection transistor to turn off the power supply protection transistor and stop any current from flowing from the first pad to the second pad.
