Abstract
This disclosure provides a nonvolatile memory device and related methods of manufacture and operation. The device may include one or more resistive random access memory (ReRAM) approaches to provide a memory device with more predictable operation. In particular, the forming voltage required by particular designs may be reduced through the use of a barrier layer, a reverse polarity forming voltage pulse, a forming voltage pulse where electrons are injected from a lower work function electrode, or an anneal in a reducing environment. One or more of these techniques may be applied, depending on the desired application and results.
