MICRO PROBLEMS. “It should be noted that a capacitor is made of a piece of insulator sandwiched by two metal plates. As device scaling following Moore’s Law, the insulator becomes thinner and thinner, the problem of charge leakage occurs and the stored data are lost. The problem leads to high power consumption in current technology.”
