Claim 18:
19. A data storage system comprising:
a semiconductor storage device including
a first substrate,
circuit elements on the first substrate,
a second substrate on the circuit elements,
a horizontal conductive layer on the second substrate,
a support layer on the horizontal conductive layer,
a stack structure including a plurality of gate electrodes, stacked to be spaced apart from each other in a direction perpendicular to an upper surface of the support layer, and a plurality of interlayer insulating layers, stacked alternately with the plurality of gate electrodes,
a channel structure penetrating through the stack structure,
a separation structure penetrating through the horizontal conductive layer, the support layer, and the stack structure and extending in a first direction,
a conductive pattern on a level between the horizontal conductive layer and a lowermost interlayer insulating layer of the plurality of interlayer insulating layers, and protruding outwardly of the separation structure from a side surface of the separation structure, the conductive pattern spaced apart from a lower surface of the horizontal conductive layer, and
an input/output pad electrically connected to the circuit element; and

a controller electrically connected to the semiconductor storage device through the input/output pad and configured to control the semiconductor storage device.
