    Simulation of Five Layers Solid-State Memory Capacitor
    (Addis Ababa University, 2010-07) Kebede, Eyob; Bekele, Mulugeta (PhD)
    Tn t his work we provided th e simulation of a five layer charge-cont rolled memory capacitor in which periodic and non-period ic metamaterials are embeddcd between the plates of a rcgul ar paralic! plate capacitor. The simulation result shows hysteretic, negative and diverging in capacitance-voltage behavior and pinchcd hysterctic charge-voltage propcrt ies in both periodic and non-periodic memcapacit ive systems. Even though the chargevo ltage hysteresis loops of both perio dic and non periodic metamaterial memcapacit ive systems are pinched, the hysteresis loop of t he per iodic system is relatively wider t han that of the non-periodic and on the average the rem nant polarized charge on the periodic memcapacitve system is higher than that of the non-periodic. This property of the periodic metamater ial memcapacitive system makes it a good candidate for non-volatile memory application over t he non-periodic one.
