Magnetic tunnel junction as a real-time entropy source: Field-Programmable Gate Array based random bit generation without post-processing

Troy Criss, Ahmed Sidi El Valli, Naomi Li +2

We demonstrate a method to generate application-ready truly random bits from a magnetic tunnel junction driven by a Field-Programmable Gate Array (FPGA). We implement a real-time f…

Tunable Random Telegraph Noise in Stable Perpendicular Magnetic Tunnel Junctions for Unconventional Computing

Ahmed Sidi El Valli, Michael Tsao, Dairong Chen +1

We demonstrate that thermally stable perpendicular magnetic tunnel junctions (pMTJs), widely used in spin-transfer torque magnetic random-access memory, can be actuated with nanose…

One Trillion True Random Bits Generated with a Field Programmable Gate Array Actuated Magnetic Tunnel Junction

Andre Dubovskiy, Troy Criss, Ahmed Sidi El Valli +3

Large quantities of random numbers are crucial in a wide range of applications. We have recently demonstrated that perpendicular nanopillar magnetic tunnel junctions (pMTJs) can pr…

Entropy-Assisted Nanosecond stochastic operation in perpendicular superparamagnetic tunnel junctions

Lucile Soumah, Louise Desplat, Nhat-Tan Phan +7

We demonstrate a good agreement between mean dwell times measured in 50~nm diameter, perpendicularly magnetized superparamagnetic tunnel junctions (SMTJ), and theoretical predictio…

Ultra-fast GHz-range swept-tuned spectrum analyzer with 20 ns temporal resolution based on a spin-torque nano-oscillator with a uniformly magnetized 'free' layer

Artem Litvinenko, Ahmed Sidi El Valli, Vadym Iurchuk +5

The advantage of an ultra-fast frequency-tunability of spin-torque nano-oscillators (STNOs) that have large (> 100MHz) relaxation frequency of amplitude fluctuations is exploited t…
