TimeCache: Using Time to Eliminate Cache Side Channels when Sharing Software
By Technical Paper Link - 14 Jun, 2021 - Comments: 0

"Abstract—Timing side channels have been used to extract cryptographic keys and sensitive documents even from trusted enclaves. Specifically, cache side channels created by reuse of shared code or data in the memory hierarchy have been exploited by several known attacks, e.g., evict+reload for recovering an RSA key and Spectre variants for leaking speculatively loaded data. In this paper, we ... » read more

Communication Algorithm-Architecture Co-Design for Distributed Deep Learning
By Technical Paper Link - 14 Jun, 2021 - Comments: 0

"Abstract—Large-scale distributed deep learning training has enabled developments of more complex deep neural network models to learn from larger datasets for sophisticated tasks. In particular, distributed stochastic gradient descent intensively invokes all-reduce operations for gradient update, which dominates communication time during iterative training epochs. In this work, we identify th... » read more

Improvement Of EUV Si Hardmask Performance Through Wet Chemistry Functionalization
By Brewer Science - 20 May, 2021 - Comments: 0

In EUV lithography, spin-on silicon hardmasks have been widely used not only as etch transfer layers, but also as assist layers to enhance the lithographic performance of resist. In this study, we demonstrate a novel approach to functionalize spin-on silicon hardmasks by hybridizing them with functional groups through a sol-gel approach. By varying the concentration and type of the functional g... » read more

HyperRec: Efficient Recommender Systems with Hyperdimensional Computing
By Technical Paper Link - 12 May, 2021 - Comments: 0

A group of researchers are taking a different approach to AI. The University of California at San Diego, the University of California at Irvine, San Diego State University and DGIST recently presented a paper on a new hardware algorithm based on hyperdimensional (HD) computing, which is a brain-inspired computing model. The new algorithm, called HyperRec, uses data that is modeled with bina... » read more

A Novel PUF Using Stochastic Short-Term Memory Time of Oxide-Based RRAM for Embedded Applications
By Technical Paper Link - 31 Mar, 2021 - Comments: 0

Abstract: "RRAM suffers from poor retention with short-term memory time when using low compliance current for programing. However, the short-term memory time exhibits ideal randomness, which can be exploited as an entropy source for physically unclonable function (PUF). In this work, we demonstrated a novel PUF utilizing the stochastic short-term memory time of oxide-based RRAM. The proposed P... » read more
