Organic non-volatile memory material and memory device

The invention provides an organic nonvolatile memory material, which comprises nano particles uniformly dispersed in the first macromolecules. The metal core of the nano particle is coated through the second macromolecule to form a core-shell structure. The first macromolecule and the second macromolecule can be formed by identical monomers through polymerization, and the polymerization degree of the first macromolecule is larger than the polymerization degree of the second macromolecule. Because the nonvolatile memory material has good uniformity, the electrical property performance of the memorizer can be stably displayed, such as the repeatable read frequency, the holding time of the data, and the on/off ratio of low voltage, low write current to high current.
