ReRAM From Material Study to CMOS Co-integration

Elmira Shahrabi

The revolution of information-technology owes to silicon-based complementary-metal-oxide (CMOS) technology. However, CMOS technology approaches its physical limitation hardening the further progress of memory devices as well as computing paradigm requiring ...

Performance improvement of chip-level CMOS-integrated ReRAM cells through material optimization

Elmira Shahrabi, Thomas La Grange, Yusuf Leblebici, Tugba Demirci

The integration of the resistive random access memory (ReRAM) with CMOS logic circuitry provides a solution to scaling limitations, and offers promising candidates for use in next generation computing applications. It is challenging to realize a reliable, ...

Reducing Metadata Leakage from Encrypted Files and Communication with PURBs

Jean-Pierre Hubaux, Bryan Alexander Ford, Ludovic Barman, Kirill Nikitin, Wouter Lueks, Matthew Joshua Underwood

Most encrypted data formats leak metadata via their plaintext headers, such as format version, encryption schemes used, number of recipients who can decrypt the data, and even the recipients’ identities. This leakage can pose security and privacy risks to ...

Negative Capacitance as Universal Digital and Analog Performance Booster for Complementary MOS Transistors

Mihai Adrian Ionescu, Christian Enz, Igor Stolichnov, Farzan Jazaeri, Ali Saeidi

Boltzmann electron energy distribution poses a fundamental limit to lowering the energy dissipation of conventional MOS devices, a minimum increase of the gate voltage, i.e. 60 mV, is required for a 10-fold increase in drain-to-source current at 300 K. Neg ...

Exploration of Negative Capacitance Devices and Technologies

Ali Saeidi

Conventional device scaling has been the main guiding principle of the MOS device engineering over these past years. However, this aggressive scaling would be eventually limited due to the inability to remove the heat generated by MOSFET devices. The power ...

Polarity-Controllable Devices and Circuits for Doping-Free 2D Electronics

Giovanni Vincenzo Resta

The growth of information technology has been sustained by the miniaturization of Complementary Metal-Oxide-Semiconductor (CMOS) Field-Effect Transistors (FETs), with the number of devices per unit area constantly increasing, as exemplified by Mooreâ s la ...

An Optimal Space Lower Bound for Approximating MAX-CUT

Mikhail Kapralov

We consider the problem of estimating the value of MAX-CUT in a graph in the streaming model of computation. At one extreme, there is a trivial 2-approximation for this problem that uses only O(log n) space, namely, count the number of edges and output hal ...

New Graph Algorithms via Polyhedral Techniques

Jakub Tarnawski

In this thesis we give new algorithms for two fundamental graph problems. We develop novel ways of using linear programming formulations, even exponential-sized ones, to extract structure from problem instances and to guide algorithms in making progress. S ...

Graph fragmentation problem: analysis and synthesis

Manuel Francesco Aprile, Pablo Romero Gómez

Vulnerability metrics play a key role in the understanding of cascading failures and target/random attacks to a network. The graph fragmentation problem (GFP) is the result of a worst-case analysis of a random attack. We can choose a fixed number of indivi ...

MPA-SSA, design and test of a 65 nm ASIC-based system for particle tracking at HL-LHC featuring on-chip particle discrimination

Yusuf Leblebici, Alessandro Caratelli, Davide Ceresa, Simone Scarfì

Particle tracking detectors for High Energy Physics need a new readout technique to cope with the increase of the collision rate foreseen for the High Luminosity LHC upgrade. In particular, the selection of interesting physics events at the first trigger s ...
