Claim 0:
1. 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 connected to the arc protection diode;
a conductive plate on the peripheral circuit structure;
a cell array structure overlapping the peripheral circuit structure in a vertical direction with the conductive plate therebetween; and
a first wiring structure connected between the arc protection diode and the conductive plate,
wherein the common source line driver comprises:
a gate on the lower substrate;
a drain in the lower substrate at a position adjacent the gate and integrated with the arc protection diode; and
a source in the lower substrate on an opposite side of the gate from the drain, and wherein a first planar area of the drain is greater than a second planar area of the source.
