| Abstract | In this paper, we analyze the fundamental vulnerabilities of Spin-Torque-Transfer RAM on magnetic field and temperature that can be exploited by adversaries with an intent to trigger soft performance failures. We present novel attack vectors and their impact on memory performance (i.e., read, write and retention). We propose a novel low-overhead clock frequency-adaptation technique to mitigate the attack. Our analysis indicate slowing the clock frequency by 85% restores 170 mV of sense margin under 300 Oe DC magnetic field. In addition, 66% operating clock slowdown allows STTRAM to tolerate over 300 Oe AC magnetic field. |
