Non-filamentary RRAM is a promising technology that features self-rectifying, forming/compliance-free, tight resistance distributions at both high and low resistance states (HRS/LRS). Direct experimental evidence for its physical switching & failure mechanisms, however, is still missing, due to the lack of suitable characterization techniques. In this work, a novel method combining the random-telegraph-noise...
Filament rupture/restoration induced by movement of defects, e.g. oxygen ions/vacancies, is considered as the switching mechanism in HfO2 RRAM. However, details of filament alteration during switching are still speculative, due to the limitations of existing experiment-based probing techniques, impeding its understanding. In this work, for the first time, an RTN-based defect tracking technique is...
As the HTTP-based segmented video delivery paradigm continues to grow in popularity, the ability to enforce differentiated classes of service (CoS) across large numbers of clients becomes increasingly important. Differentiated services are an important monetization technique for content service providers. In over-the-top (OTT) video delivery, client-based CoS enforcement is necessary for federated...
At-speed scan testing has become mandatory due to the extreme CMOS technology scaling. The two main at-speed scan testing schemes are namely Launch-Off-Shift (LOS) and Launch-Off-Capture (LOC). As it can be easily implemented, LOC has been widely investigated in the literature in the last few years, especially regarding test power consumption. Conversely, LOS has received much less attention. In this...
