Resistive memory cell

摘要

Semiconductor memory devices, resistive memory devices, memory cell structures, and methods of forming a resistive memory cell are provided. One example method of a resistive memory cell can include a number of dielectric regions formed between two electrodes, and a barrier dielectric region formed between each of the dielectric regions. The barrier dielectric region serves to reduce an oxygen diffusion rate associated with the dielectric regions.
