Abstract:
Emerging non-volatile memory (NVM) technologies offer unique advantages in terms of energy efficiency, latency, and features such as computing-in-memory. As a result of these advantages, emerging NVM technologies are considered an ideal substrate for computation and storage in future-generation neuromorphic platforms. These technologies need to be evaluated for the most fundamental reliability and security issues. In this paper, we present NeuroHammer, a security threat in ReRAM crossbars caused by thermal crosstalk between memory cells. It is demonstrated that bit-flips can be deliberately induced in ReRAM devices in a crossbar by systematically writing adjacent memory cells. A simulation flow is developed for the evaluation of NeuroHammer and the impact of physical parameters on the effectiveness of the attack. Finally, we discuss the security implications in the context of possible attack scenarios.
