CBRAM devices as binary synapses for low-power stochastic neuromorphic systems: auditory (cochlea) and visual (retina) cognitive processing applications

M. Suri, O. Bichler, D. Querlioz, G. Palma, E. Vianello, D. Vuillaume, C. Gamrat, B. de Salvo

In this work, we demonstrate an original methodology to use Conductive-Bridge RAM (CBRAM) devices as binary synapses in low-power stochastic neuromorphic systems. A new circuit architecture, programming strategy and probabilistic STDP learning rule are proposed. We show, for the first time, how the…

Low frequency dielectric loss of metal/insulator/organic semiconductor junctions in ambient conditions

Romuald Ledru, Stéphane Pleutin, Bruno Grouiez, Damien Zander, H. Bejbouji, Kamal Lmimouni, Dominique Vuillaume

The complex admittance of metal/oxide/pentacene thin film junctions is investigated under ambient conditions. At low frequencies, a contribution attributed to proton diffusion through the oxide is seen. This diffusion is shown to be anomalous and is believed to be also at the origin of the bias…

Phonons in Slow Motion: Dispersion Relations in Ultra-Thin Si Membranes

John Cuffe, Emigdio Chavez, Andrey Shchepetov, Pierre-Olivier Chapuis, El Houssaine El Boudouti, Francesc Alzina, Timothy Kehoe, Jordi Gomis-Bresco, Damian Dudek, Yan Pennec, Bahram Djafari-Rouhani, Mika Prunnila, Jouni Ahopelto, Clivia. M. Sotomayor Torres

We report the changes in dispersion relations of hypersonic acoustic phonons in free-standing silicon membranes as thin as \sim 8 nm. We observe a reduction of the phase and group velocities of the fundamental flexural mode by more than one order of magnitude compared to bulk values. The…
