Apparatuses including capacitors and related systems

An apparatus, comprising:

• data lines extending in a first direction;
• access lines extending in a second direction, orthogonal to the first direction;
• capacitors adjacent to the access lines and comprising electrodes extending in a third direction, orthogonal to each of the first direction and the second direction, the capacitors comprising elongated structures including junctionless nanowires configured as the electrodes of the capacitors;
• a staircase structure adjacent to one or more of a longitudinal end and a lateral side of the electrodes of the capacitors;
• and
• conductive contacts on individual levels of the staircase structure, each of the capacitors corresponding to a respective level of the staircase structure sharing a common conductive contact.

A system, comprising:

• a processor;
• and
• electronic devices operably coupled to the processor, one or more of the electronic devices comprising:
• capacitors overlying a material, a major plane of individual capacitors substantially parallel with a major plane of the material;
• gate structures adjacent to the capacitors, one or more of the gate structures coupled to respective capacitors;
• conductive lines connecting individual gate structures, the conductive lines extending substantially transverse to the major plane of the material, the individual gate structures laterally adjacent to respective capacitors;
• access devices adjacent to the conductive lines, the individual capacitors and respective access devices sharing a common gate structure;
• and
• nanowires extending substantially parallel with the major plane of the material, the individual capacitors and respective access devices sharing a common conductive material of the nanowires.
