The first cross-modal ablation of memory mechanisms in spiking neural networks, across visual (N-MNIST, DVS-Gesture, Caltech101-DVS) and audio (SHD, SSC) benchmarks. Hopfield memory reaches 97.68% on visual tasks but 76.15% on audio; the full hybrid has the best cross-modal average (89.99%); an optimized HGRN reaches 719× energy efficiency versus dense ANNs at 99.3% sparsity.
