Abstract
A resistive memory device includes a first electrode, a memristor coupled in electrical series with the first electrode, a second electrode coupled in electrical series with the memristor, a selector coupled in electrical series with the second electrode, and a third electrode coupled in electrical series with the selector. The memristor includes oxygen or nitrogen elements. The selector includes a composite dielectric material of a first dielectric material, a second dielectric material that is different from the first dielectric material, and a dopant material including a cation having a migration rate faster than the oxygen or the nitrogen elements of the memristor. The first dielectric material and the second dielectric material are present in a ratio ranging from 1:9 to 9:1, and a concentration of the dopant material in the composite dielectric material ranges from about 1% up to 50%.
