Resistance drift in phase change materials is characterized in amorphous phase change memory line-cells from 300 K to 125 K range and is observed to follow the previously reported power-law behavior with drift coefficients in the 0.07 to 0.11 range in dark. While these drift coefficients measured in dark are similar to commonly observed drift coefficients (~0.1) at and above room temperature, measurements under light show a significantly lower drift coefficients (0.05 under illumination versus…

Stopping Resistance Drift in Phase Change Memory Cells

The results suggest that structural relaxations alone cannot account for resistance drift, additional mechanisms are contributing to this phenomenon.
