Example 4b: The apparatus of example 3b, wherein the first set of capacitors includes a first capacitor which includes: a first layer coupled to the first conductive electrode, wherein the first layer comprises a first metal; a second layer around the first layer, wherein the second layer comprises a first conductive oxide; a third layer comprising a ferroelectric dielectric material, wherein the third layer is around the second layer; a fourth layer around the third layer, wherein the fourth layer comprises a second conductive oxide, wherein the fourth layer is around the third layer; and a fifth layer around the fourth layer, wherein the fifth layer comprises a second metal, wherein a first plate-line is adjacent to part of the fifth layer.
Example 5b: The apparatus of example 4b, wherein: the first layer has a first circumference; the second layer has a second circumference; the third layer has a third circumference; the fourth layer has a fourth circumference; and the fifth layer has a fifth circumference, wherein the fifth circumference is larger than the fourth circumference, wherein the fourth circumference is larger than the third circumference, wherein the third circumference is larger than the second circumference, wherein the second circumference is larger than the first circumference.
