In this paper we report results on PCM endurance failure characterization. We show that endurance failure is related to SET pulse features and we analyze and model SET operation to obtain a better understanding and improve endurance performance. Results give interesting insights on the crystallization process of GST material. SET obeys to a constant energy law. Fast SET pulses require high power; slow SET pulses can be implemented in low power applications. Results may be used for optimized SET/RESET operation to achieve better endurance.
