α-In2Se3-based FeSFETs can operate as sustainable synaptic devices by exploiting polarization switching driven by both out-of-plane and in-plane dipole components. When the devices enter a fatigued state, current-annealing assisted by conductance modulation can markedly recover and extend their endurance. Furthermore, such current annealing can be selectively and dynamically applied to defective cells in real time at the system level, while sustaining optimized and practical power consumption. More details can be found in the Research Article by TaeWan Kim, Hagyoul Bae, and co-workers (DOI: 10.1002/advs.202600064).
