ABSTRACT:
Disclosed herein are new resistive memory devices having one or more buffers layer surrounding a dielectric layer. By inserting one or more buffer layers around the dielectric layer of the device, the resistive ratio of the device is highly enhanced. For example, tests using this unique stack structure have revealed a resistance ratio of approximately 1000× over conventional electrode-dielectric-electrode stack structures found in resistive memory devices. This improvement in the resistance ratio of the resistive memory device is believed to be from the improved interface coherence, and thus smoother topography, between the buffer layer(s) and the dielectric layer.
