Description:

The EECS Department welcomes Prof. Pedram Khalili, Associate Professor of Electrical Engineering and Computer Science Dept. at Northwestern University.

Khalili will present a talk entitled "Computing with Nanoscale Magnets", on Wednesday, May 23 at 2:00 PM in the Ford ITW Room.

Abstract: The fast growth of memory-intensive applications in machine learning and autonomous systems, combined with the slowing pace of traditional CMOS scaling, have created new demands and opportunities for both embedded and discrete memories in electronic systems. Spintronic devices – which combine data storage in a nano-magnet with electrical readout using spin-dependent electronic transport phenomena – are prime contenders to address this need. They combine nonvolatile operation and nanosecond speed with high endurance required for embedded and random access memory applications. For the first time in more than two decades, this has resulted in the introduction of fundamentally new device types – i.e. magnetic tunnel junctions (MTJs) used for magnetic random access memory (MRAM) – into volume manufacturing in semiconductor fabs. We will review recent progress and perspectives of spintronics focusing on two areas: (i) How to build memory devices with unprecedented energy efficiency, speed, and integration density, with an eye on applications in advanced nodes below 10 nm, (ii) How emerging device concepts in spintronics, which frequently emerge from a desire to build better memory and computing elements, can be adapted to other types of devices that are important for the Internet of Things (IoT), with examples being sensors, microwave detectors, and random number generators. We will discuss progress in the development of magnetic tunnel junctions controlled by electric fields, which exhibit the most energy-efficient nonvolatile memory cells developed to date (< 5 fJ/bit with write times < 1 ns), and discuss some of their current materials, device, and circuit-level opportunities and challenges. We then discuss our recent results and emerging opportunities in the development of microwave diodes with detection sensitivities > 75 mV/µW, based on engineering of interfacial anisotropy and spin-orbit interaction in nanostructures.

Bio: Prof. Pedram Khalili is Associate Professor of Electrical Engineering and Computer Science at Northwestern University. He joined Northwestern in September 2017, where his team works on developing the computing systems of the future, starting from novel nano-scale devices/materials that enable systems with unprecedented performance and energy efficiency. Previously Pedram was an adjunct assistant professor of electrical and computer engineering at UCLA from 2013-2017, where he co-led the memory program within the NSF TANMS center, focusing on development of Voltage-Controlled MRAM. During 2009-2014, at UCLA he co-led two DARPA multi-institution programs, focusing on the development of spin-transfer-torque magnetic random access memory (STT-MRAM) and non-volatile logic (NVL), working with several industry and university partners. These programs resulted in the world’s fastest and lowest-power memory technologies at the time, and accelerated the adoption of MRAM by major players in the semiconductor industry. In 2012 he co-founded Inston Inc., where he served as chief technology officer until recently. In this role he led the team that ranked top-6 out of more than 3,000 startups worldwide in the Cisco Innovation Grand Challenge 2015. He was an IEEE Intermag best paper award finalist in 2008. He has published more than 90 journal publications with over 3,200 citations and an h-index of 31, and has 15 issued US patents. His professional activities have included serving as a guest editor for Spin (World Scientific), and serving on the technical program committee of the Joint MMM/Intermag Conference.
