Cross-sectional structure of a PCM cell.
Resistance of the PCM cells before and after performing RESET operations. The curves with circle symbol show the low resistance of cells and the curves with triangle symbol show the high resistance of cells achieved after reset.
RESET resistance of the PCM cells vs pulse amplitude.
Temperature distribution of a PCM cell after RESET (a) 3.5 V pulse amplitude and 50 ns pulse width; (b) 3.5 V pulse amplitude and 0.8 ns pulse width.
