In principle, the memory application is based on the hysteretic behavior of polarization with electric field as shown in Fig 1-2. When an external voltage is applied to a ferroelectric capacitor, there is a net ionic displacement in the unit cells of the ferroelectric material. The individual unit cells interact constructively with their

What is Capacitor and How Does It Work ?
Capacitor Dielectric Working Principle. Let''s take a look how the dielectric can increase the capacitance of the capacitor. A dielectric contains molecules that are polar which means that they can change their orientation based on the charges on the two plates. So the molecules align themselves with the electric field in such a way enabling ...
Memristor
The memristor is a new generation of memory and computing power. Symbol of Memristor Working Principle of Memristor. The working principle of a memristor is based on the relationship between the charge q (electric charge) and the flux φ (magnetic flux) linking the two terminals of the device. This relationship can be expressed by the equation:
