TL;DR: In this paper, a nonvolatile full adder based on logic-in-memory architecture using magnetic tunnel junctions (MTJs) in combination with metal oxide semiconductor (MOS) transistors is presented.
Journal ArticleDOI
VLSI Implementation of Deep Neural Network Using Integral Stochastic Computing
TL;DR: The proposed architecture uses integer stochastic streams and a modified Finite State Machine-based tanh function to improve the performance and reduce the latency compared to existing stochastically architectures for DNN.
Proceedings ArticleDOI
VLSI implementation of deep neural networks using integral stochastic computing
TL;DR: This paper proposes an integer form of stochastic computation and introduces some elementary circuits and proposes an efficient implementation of a DNN based on integral SC, and considers a quasi-synchronous implementation that yields 33% reduction in energy consumption with respect to the binary radix implementation without any compromise on performance.
Journal ArticleDOI
An Overview of Nonvolatile Emerging Memories— Spintronics for Working Memories
TL;DR: Current status of spintronics developments including not only STT-MRAM but also nonvolatile logic LSI is described, which are particularly suitable for working memory applications.
