Abstract

Ti-doped Ge₂Sb₂Te₅ (GSTT) materials have been investigated for phase change memory (PCM) applications. Compared with GST, GSTT5.67% phase change material has a higher crystallization temperature (∼230°C), a higher crystallization activation energy (2.79 eV) and a better data retention ability (∼134°C for 10-year). The PCM cell based on GSTT5.67% exhibits lower power consumption than GST based one. Endurance up to 1 × 10⁴ cycles with high/low resistance ratio of over one order of magnitude has been achieved.
