Abstract
A memcapacitor according to an embodiment includes a first electrode, a first dielectric layer provided on the first electrode, a plurality of variable resistance portions provided separately from each other on the first dielectric layer, a second dielectric layer provided on the first dielectric layer and between the variable resistance portions, and a second electrode provided on the variable resistance portions and the second dielectric layer. Each of the variable resistance portions is formed of a material that allows diffusion of metal atoms constituting the second electrode to inside of the variable resistance portion, and the second dielectric layer is formed of a material that prevents diffusion of the metal atoms constituting the second electrode to inside of the second dielectric layer.
