Test Methodology Development for Investigating CeRAM at Elevated Temperatures

Abstract-Correlated electron RAM (CeRAM) device test structures utilizing C-doped NiO were fabricated and electrically characterized to determine functionality in extreme environments. CeRAM devices were demonstrated to repeatedly cycle at temperatures up to 200°C while maintaining a substantial memory window of over 1000 x. Careful selection of compliance current when sweeping the high resistance state (OFF) is required for optimal device performance. The presence of a temperature dependent leakage current in the OFF state results in reducing OFF resistance at elevated temperatures.
