Research Bits: December 11


Diamond device with high breakdown voltage Researchers from the University of Illinois at Urbana-Champaign developed diamond p-type lateral Schottky barrier diodes they say have the highest breakdown voltage and lowest leakage current compared to previous diamond devices. The diamond device can sustain high voltage, approximately 5 kV, although the voltage was limited by setup of measurement a... » read more

Diamond Semiconductor: Highest Breakdown Voltage, Lowest Leakage Current


A technical paper titled "Diamond p-Type Lateral Schottky Barrier Diodes With High Breakdown Voltage (4612 V at 0.01 mA/Mm)" was published by researchers at University of Illinois at Urbana–Champaign. Abstract "Diamond p-type lateral Schottky barrier diodes (SBDs) with a 2- μm -thick drift layer are fabricated with and without Al2O3 field plates. Schottky contacts composed of Mo (50 nm) ... » read more

Week In Review: Automotive, Security, Pervasive Computing


Stellantis and Foxconn formed a 50/50 joint venture called SiliconAuto, to be headquartered in the Netherlands. The goal is to close the gap between supply and demand for chips used in computer-controlled features and modules, especially for electric vehicles (EVs). The U.S. Department of Justice created a National Security Cyber Section within its National Security Division to increase the ... » read more

Uncovering The Size, Structure, And Operation Of DRAM Subarrays And Showing Experimental Results Supporting The Cause Of Rowhammer


A technical paper titled “X-ray: Discovering DRAM Internal Structure and Error Characteristics by Issuing Memory Commands” was published by researchers at Seoul National University and University of Illinois at Urbana-Champaign. Abstract: "The demand for accurate information about the internal structure and characteristics of dynamic random-access memory (DRAM) has been on the rise. Recen... » read more

Research Bits: Sept. 20


Multi-mode memristors Researchers from ETH Zurich, the University of Zurich, and Empa built a new memristor that can operate in multiple modes and could potentially be used to mimic neurons in more applications. “There are different operation modes for memristors, and it is advantageous to be able to use all these modes depending on an artificial neural network’s architecture,” said R... » read more

Security Research: Technical Paper Round-Up


A number of hardware security-related technical papers were presented at recent conferences, including the August 2022 USENIX Security Symposium and IEEE’s International Symposium on Hardware Oriented Security and Trust (HOST). Topics include side-channel attacks and defenses (including on-chip mesh interconnect attacks), heterogeneous attacks on cache hierarchies, rowhammer attacks and mitig... » read more

Microarchitectural Side-Channel Attacks and Mitigations on the On-Chip Mesh Interconnect


This new technical paper titled "Don't Mesh Around: Side-Channel Attacks and Mitigations on Mesh Interconnects" was presented by researchers at University of Illinois at Urbana-Champaign, MIT, and Texas Advanced Computing Center at the USENIX Security Symposium in Boston in August 2022. Abstract: "This paper studies microarchitectural side-channel attacks and mitigations on the on-chip mes... » read more

Research Bits: April 19


Processor power prediction Researchers from Duke University, Arm Research, and Texas A&M University developed an AI method for predicting the power consumption of a processor, returning results more than a trillion times per second while consuming very little power itself. “This is an intensively studied problem that has traditionally relied on extra circuitry to address,” said Zhiy... » read more
