Skyrmionic Synapses

Nanoscale multilayer skyrmion synapses operating at room temperature for deep spiking neural networks.

Nanoscale multilayer skyrmion synapse using repeated [HM1/FM/HM2] stacks (n=4 repeats). The multilayer structure stabilizes skyrmions at room temperature (300K).

Features:

  • 6 discrete synaptic states
  • Non-volatile, CMOS-compatible

Key Results: 98.61% accuracy with only 6 synaptic states (deep SNN)
