    摘要: A capacitor of a semiconductor device and a memory device including the same are provided. The capacitor includes a lower electrode, a dielectric layer which has a plurality of band gaps, formed on the lower electrode, and an upper electrode formed on the dielectric layer. The dielectric layer includes a first dielectric layer that has a first band gap and is formed on the lower electrode, a second dielectric layer that has a second band gap and is formed on the first dielectric layer, and a third dielectric layer that has a third band gap and is formed on the second dielectric layer.
