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 comprising tiers each comprising:
conductive material comprising alpha phase tungsten; and
insulative material vertically neighboring the conductive material;
a staircase structure having steps comprising edges of at least some of the tiers of the stack structure;
tungsten pad structures on at least some of the steps of the staircase structure and individually comprising a lower concentration of the alpha phase tungsten than the conductive material of the tiers of the stack structure, at least one of the tungsten pad structures having a horizontal center offset from a horizontal center of one of the steps directly vertically thereunder; and
conductive contact structures on the tungsten pad structures.
