Memristors with diffusive dynamics as synaptic emulators for neuromorphic computing
Zhongrui Wang,Saumil Joshi,Sergey Savel'ev,Hao Jiang,Rivu Midya,Peng Lin,Miao Hu,Ning Ge,John Paul Strachan,Zhiyong Li,Qing Wu,Mark Barnell,Geng Lin Li,Huolin L. Xin,R. Stanley Williams,Qiangfei Xia,Jianhua Yang +16 more
TL;DR: The diffusive Ag-in-oxide memristor and its dynamics enable a direct emulation of both short- and long-term plasticity of biological synapses, representing an advance in hardware implementation of neuromorphic functionalities.
Journal ArticleDOI
Memristive crossbar arrays for brain-inspired computing
Qiangfei Xia,Jianhua Yang +1 more
TL;DR: The challenges in the integration and use in computation of large-scale memristive neural networks are discussed, both as accelerators for deep learning and as building blocks for spiking neural networks.
Journal ArticleDOI
Analogue signal and image processing with large memristor crossbars
Can Li,Miao Hu,Miao Hu,Yunning Li,Hao Jiang,Ning Ge,Eric Montgomery,Jiaming Zhang,Wenhao Song,Noraica Davila,Catherine Graves,Zhiyong Li,John Paul Strachan,Peng Lin,Zhongrui Wang,Mark Barnell,Qing Wu,R. Stanley Williams,Jianhua Yang,Qiangfei Xia +19 more
TL;DR: It is shown that reconfigurable memristor crossbars composed of hafnium oxide memristors on top of metal-oxide-semiconductor transistors are capable of analogue vector-matrix multiplication with array sizes of up to 128 × 64 cells.
Journal ArticleDOI
Fully memristive neural networks for pattern classification with unsupervised learning
Zhongrui Wang,Saumil Joshi,Sergey Savel'ev,Wenhao Song,Rivu Midya,Yunning Li,Mingyi Rao,Peng Yan,Shiva Asapu,Ye Zhuo,Hao Jiang,Peng Lin,Can Li,Jung Ho Yoon,Navnidhi K. Upadhyay,Jiaming Zhang,Miao Hu,John Paul Strachan,Mark Barnell,Qing Wu,Huaqiang Wu,R. Stanley Williams,Qiangfei Xia,Jianhua Yang +23 more
TL;DR: It is shown that a diffusive memristor based on silver nanoparticles in a dielectric film can be used to create an artificial neuron with stochastic leaky integrate-and-fire dynamics and tunable integration time, which is determined by silver migration alone or its interaction with circuit capacitance.
Journal ArticleDOI
Memristor―CMOS Hybrid Integrated Circuits for Reconfigurable Logic
Qiangfei Xia,Warren Robinett,Cumbie Michael W,Neel Banerjee,Thomas J. Cardinali,Jianhua Yang,Wei Wu,Xuema Li,William M. Tong,Dmitri B. Strukov,Gregory S. Snider,Gilberto Medeiros-Ribeiro,R. Stanley Williams +12 more
TL;DR: Hybrid reconfigurable logic circuits were fabricated by integrating memristor-based crossbars onto a foundry-built CMOS (complementary metal-oxide-semiconductor) platform using nanoimprint lithography, as well as materials and processes that were compatible with the CMOS.
