Claim 2:
3. A selector, comprising, in the order of:
a first electrode;
an ion supply layer;
a diffusion control layer;
a switching layer; and
a second electrode,
wherein the ion supply layer is doped with a metal, and wherein the doped metal diffuses toward the second electrode;
wherein the doped metal diffuses from the ion supply layer into the switching layer so that metal concentration distribution inside the switching layer changes to generate metal filaments;
wherein the diffusion control layer serves to adjust electrical characteristics related to the generated metal filaments as an amount of the diffusing metal is adjusted in proportion to a thickness of the diffusion control layer;
wherein at least one electrical characteristic of a threshold voltage (Vth), a hold voltage (Vh) and a selectivity increases as the thickness of the diffusion control layer increases; and
wherein when the thickness of the diffusion control layer is 0 nm to 2 nm, the threshold voltage (Vth) is adjusted to 0.6 V to 1 V, the hold voltage (Vh) is adjusted to 0 V to 0.25 V, and the selectivity is adjusted to 4.59×105 to 3.10×106.
