Atomic migration on Phase Change Memory devices with wall architecture has been experimentally investigated and a quantitative model including electrical, thermal, and mechanical driving forces has been developed. The experimental results collected by driving the device with programming pulses with direct and reverse polarity have been accounted for. Comparison with data of atomic migration on heavily cycled cells is also provided.

Abstract
Atomic migration on Phase Change Memory devices with wall architecture has been experimentally investigated and a quantitative model including electrical, thermal, and mechanical driving forces has been developed. The experimental results collected by driving the device with programming pulses with direct and reverse polarity have been accounted for. Comparison with data of atomic migration on heavily cycled cells is also provided.File in questo prodotto:
