A method of forming an array of capacitors comprises forming elevationally-extending and longitudinally-elongated capacitor electrode lines over a substrate. Individual of the capacitor electrode lines are common to and a shared one of two capacitor electrodes of individual capacitors longitudinally along a line of capacitors being formed. A capacitor insulator is formed over a pair of laterally-opposing sides of and longitudinally along individual of the capacitor electrode lines. An elevationally-extending conductive line is formed over the capacitor insulator longitudinally along one of the laterally-opposing sides of the individual capacitor electrode lines. The conductive line is cut laterally through to form spaced individual other of the two capacitor electrodes of the individual capacitors. Other methods are disclosed, including structures independent of method of manufacture.
