Atreya Majumdar,Marc Bocquet,Tifenn Hirtzlin,Axel Laborieux,Jacques-Olivier Klein,Etienne Nowak,Elisa Vianello,Jean-Michel Portal,Damien Querlioz +8 more
TL;DR: In this article, a model of the weak RESET process in hafnium oxide RRAM is presented and integrated into the PyTorch deep learning framework for training Binarized Neural Networks for handwritten digit recognition and object classification.
Journal ArticleDOI
Experimental Demonstration of Multilevel Resistive Random Access Memory Programming for up to Two Months Stable Neural Networks Inference Accuracy
E. Esmanhotto,Tifenn Hirtzlin,Djohan Bonnet,N. Castellani,Jean-Michel Portal,Damien Querlioz,Elisa Vianello +6 more
TL;DR: In this paper , a 32 × 32 in-memory computing system, fabricated in a hybrid complementary metaloxide-semiconductor (CMOS)/hafnium oxide technology, was used to classify heart arrhythmia from electrocardiogram.
Proceedings ArticleDOI
Power efficiency optimization of charge pumps in embedded low voltage NOR flash memory
TL;DR: A new concept for improving efficiency of a charge pump system is presented, based on a set of elementary charge pumps connected in parallel in addition to the detection of the number of memory cells to be programmed at the same time.
Journal ArticleDOI
1S1R Optimization for High‐Frequency Inference on Binarized Spiking Neural Networks
J. Minguet Lopez,Quentin Rafhay,M. Dampfhoffer,L. Reganaz,N. Castellani,V. Meli,S. Martin,L. Grenouillet,Gabriel Navarro,T. Magis,C. Carabasse,Tifenn Hirtzlin,Elisa Vianello,Damien Deleruyelle,Jean-Michel Portal,G. Molas,Francois Andrieu +16 more
TL;DR: In this article , a 1S1R (1 Selector 1 Resistor) device composed of a HfO2-based OxRAM memory stacked on a GeSeSb•N-based ovonic threshold switch (OTS) back-end selector is proposed for high-density binarized SNNs (BSNNs) synaptic weight hardware implementation.
Proceedings ArticleDOI
Experimental demonstration of Single-Level and Multi-Level-Cell RRAM-based In-Memory Computing with up to 16 parallel operations
E. Esmanhotto,Tifenn Hirtzlin,N. Castellani,S. Martin,Bastien Giraud,Francois Andrieu,J. F. Nodin,Damien Querlioz,Jean-Michel Portal,Elisa Vianello +9 more
TL;DR: This work demonstrates experimentally an RRAM-based IMC logic concept with strong resilience to RRAM variability, even after one million endurance cycles, a new milestone for RRAM in-memory logic.
