Abstract

We have been researching the polymer nonvolatile memory-cell based on electrical bi-stability. The polymer nonvolatile memory-cell was the 4F² embedded with Ag nano-crystals in conductive polymer. The structure of polymer nonvolatile memory-cell was PVK(poly(N-vinylcarbazole) / Ag nano-crystals / PVK between the Al electrodes. The Ag nano-crystals were formed by using the curing process after evaporate several nanometers of Ag layer. The polymer nonvolatile memory-cell embedded with Ag nano-crystals showed the memory magin(ratio of I_on to I_off) is ~5.0 × 10¹. The retention time is more than 10⁵ seconds.
