Abstract:

Energy-efficiency, robustness and security are three important design metrics for broad range of electronic applications. Conventional CMOS circuits suffer from variability and leakage. Spintronic circuits eliminate the leakage however they suffer from variability, write power, write latency and poor read margin. In the first part of the talk, I will describe adaptive write current boosting and adaptive voltage biasing to mitigate above mentioned challenges in spintronic memories. In the second part of the talk, I will discuss the issues with conventional security primitive design using CMOS. I will introduce intentional contention injection and embedded latches to enhance the quality of security primitives. Finally, I will show the application of spintronics in high-quality security primitive design.
