US Patent 7612358 Nonvolatile nanochannel memory device using mesoporous material

A nonvolatile nanochannel memory device using a mesoporous material. Specifically, a memory device is composed of a mesoporous material that is able to form nanochannels, in which a memory layer having metal nanoparticles or metal ions fed into the nanochannels is disposed between an upper electrode and a lower electrode. Thus, the memory device has high processability, and manifests excellent reproducibility and uniform performance.
