Abstract
The present disclosure, in some embodiments, relates to a resistive random access memory (RRAM) cell. The RRAM cell has a bottom electrode disposed over a lower interconnect layer and a data storage layer having a first thickness over the bottom electrode. A capping layer is disposed over the data storage layer. The capping layer has a second thickness that is in a range of between approximately 2 and approximately 3 times thicker than the first thickness. A top electrode is disposed over the capping layer and an upper interconnect layer is disposed over the top electrode.
