Disclosed herein are transistors, memory cells, and arrangements thereof. For example, in some embodiments, an integrated circuit (IC) structure may include a plurality of transistors, wherein the transistors are distributed in a hexagonally packed arrangement. In another example, in some embodiments, an IC structure may include a memory cell including an axially symmetric transistor coupled to an axially symmetric capacitor, wherein the axis of the transistor is aligned with the axis of the capacitor.
