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.
