Résumé
Spintronic devices, such as magnetic tunnel junctions (MTJs), are promising for space applications due to their radiation hardness and nonvolatility. However, as semiconductor technology advances, CMOS peripheral circuits are becoming vulnerable to double node upset (DNU) as well as triple node upset (TNU). This brief proposes two nonvolatile and robust latch designs primarily composed of MTJs and C-elements (CEs). Both designs offer nonvolatility and self-recovery from multiple-node upsets. Simulation results demonstrate that the proposed latches provide nonvolatility and complete protection against multiplenode upsets with balanced overhead.
