In this paper, we investigate the link between various resistive memory (RRAM) electrical characteristics: endurance, window margin (WM), and retention. For this purpose, several RRAMs are characterized using various resistive layers and bottom electrodes. By focusing on one technology and optimizing programming conditions (current, voltage, and time), we establish a tradeoff between endurance and...
In this paper, a detailed reliability analysis of metal-oxide CBRAM devices is presented. We demonstrated that the addition of a thin metal-oxide layer in the bottom of the memory stack significantly increases the ROFF and the memory window (more than 1 decade), with improved endurance performance. At the same time, high thermal stability was also achieved (window margin constant during more than...
