Magnetic Tunnel Junctions for Timekeeping in Intermittent Computing Systems
Nikola Vuk Maruszewski, Jordan Athas, Allison Fleming, Christian Duffee, Eren Yildiz, Saad Ahmed, et al.
Batteryless intermittent systems run unattended for years, but power failures erase timekeeping state, corrupting sensing, scheduling, and coordination. State-of-the-art timekeepers infer elapsed time from capacitor discharge; however, the capacitor must be sized for the longest…
