Claim 3:
4. An integrated circuit device comprising:
a peripheral circuit structure comprising a lower substrate, an arc protection diode in the lower substrate, and a common source line driver that comprises a transistor connected to the arc protection diode;
a cell array structure that overlaps the peripheral circuit structure in a vertical direction and comprises a memory stack comprising a plurality of gate lines stacked in the vertical direction and a channel structure penetrating the plurality of gate lines in the vertical direction;
a conductive plate between the peripheral circuit structure and the cell array structure; and
a first wiring structure connected between the arc protection diode and the conductive plate,
wherein the transistor of the common source line driver comprises:
a gate on the lower substrate;
a source in the lower substrate at a position adjacent a first side of the gate; and
a drain in the lower substrate at a position adjacent a second side of the gate and integrated with the arc protection diode,
wherein a first planar area of the drain is greater than a second planar area of the source.
