Abstract
A nonvolatile memory device includes a first conductive unit, a second conductive unit, and a storage layer. The first conductive unit has a first work function. The second conductive unit has a second work function smaller than the first work function. The storage layer is provided between the first conductive unit and the second conductive unit. The storage layer is made using a source material including an aromatic diamine molecule and an aromatic tetracarboxylic dianhydride molecule. An ionization potential of the aromatic diamine molecule is greater than the first work function. An electron affinity of the aromatic tetracarboxylic dianhydride molecule is less than the second work function.
