Claim 17:
18. An electronic system, comprising:
a processor device operably coupled to an input device and an output device; and
a memory device operably coupled to the processor device and comprising:
a stack structure including tiers each comprising conductive material and insulative material vertically neighboring the conductive material, the stack structure having a memory array region and a staircase region horizontally neighboring the memory array region;
pillar structures comprising semiconductive material within horizontal boundaries of the memory array region and vertically extending through the stack structure;
a staircase structure within horizontal boundaries of the staircase region and having steps comprising edges of at least some of the tiers of the stack structure;
conductive contact structures on the steps of the staircase structure; and
transistors vertically overlying the stack structure and within the horizontal boundaries of the staircase region, at least one of transistors comprising:
a first indium-containing structure on one of the conductive contact structures;
a second indium-containing structure over the first indium-containing structure;
a third indium-containing structure vertically interposed between the first indium-containing structure and the second indium-containing structure, the third indium-containing structure having one or more of a lower atomic concentration of indium and a greater atomic concentration of oxygen than each of the first indium-containing structure and the second indium-containing structure;
at least one gate electrode horizontally neighboring and within vertical boundaries of the third indium-containing structure; and
gate dielectric material horizontally interposed between the third indium-containing structure and the at least one gate electrode, the gate dielectric material and the third indium-containing structure each substantially confined within a horizontal area of the first indium-containing structure.
