The first time a device is operated after fabrication the self-directed channel is formed during application of a positive potential to the top electrode. The potential required for this operation is typically the same as required during normal device operation. This first operation generates Sn ions from the SnSe layer and forces them into the ‘active’ Ge2Se3 layer, where they undergo a chemical reaction. During this reaction, the glass network is distorted to provide conductive channels for the movement of Ag+ during device operation. The resistance is tunable in the lower and higher directions by movement of Ag into or away from these channels through application of either a positive or negative potential, respectively, across the device. Knowm memristors are Ag+ ion SDC memristor where the active layer has been doped to enhance and optimize the memristors properties.
| Element | Description |
| W/Tungsten | Analog state retention with modest/fast switching response. |
| C/Carbon | Reduced analog state retention. Very low switching energy. Fastest switching response. |
| Sn/Tin | Analog state retention. Medium switching response. |
| Cr/Chromium | Analog state retention. Highest thresholds. Slowest switching response. |
