Claim 12:
13. An integrated circuit device comprising:
a peripheral circuit region comprising a peripheral circuit structure, wherein the peripheral circuit structure comprises a lower substrate, an arc protection diode in the lower substrate, and a common source line driver connected to the arc protection diode;
a cell region comprising a cell array structure overlapping the peripheral circuit structure in a vertical direction, wherein the cell region is vertically connected to the peripheral circuit region; and
a conductive plate comprising a conductive region, wherein the conductive plate is between the peripheral circuit structure and the cell array structure,
wherein the common source line driver comprises a transistor that comprises a gate, a source in the lower substrate adjacent a first side of the gate, and a drain in the lower substrate adjacent a second side of the gate and connected to the arc protection diode,
wherein the cell array structure comprises a plurality of gate lines stacked in the vertical direction on the conductive plate and a channel structure penetrating the plurality of gate lines in the vertical direction,
wherein the peripheral circuit structure further comprises a first wiring structure connected between the arc protection diode and the conductive plate,
wherein the drain of the transistor is integrated with the arc protection diode, and
wherein a length of the drain is greater than a length of the source in a channel length direction of the transistor.
