Metal-Oxide-Semiconductor (MOS) Fundamentals
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric.

Capacitors - SparkFun Learn
The fundamental storage cell within DRAM is composed of two elements: a transistor and a capacitor. When a bit needs to be put in memory, the transistor is used to charge or discharge the capacitor. A charged capacitor represents a logic high, or ''1'', while a discharged capacitor represents a logic low, or ''0''.
