Oxidized MoS 2 ‐Based Multifunctional Memristive Hardware for Energy‐Efficient mmWave Signal Processing and In‐Memory Matrix Multiplication

ABSTRACT Next‐generation 6G communication systems necessitate hardware that simultaneously manages high‐frequency signal routing and massive matrix‐level computations under extreme constraints. However, conventional digital architectures suffer from high power dissipation and area overhead. Here, we report an oxidized molybdenum disulfide (MoS 2 )‐based memristive platform that integrates nonvolatile radio‐frequency (RF) switching and energy‐efficient vector–matrix multiplication. By implementing a controlled thermal oxidation process, we achieve stable resistive switching with low switching energy and zero‐static power consumption, while maintaining a high cutoff frequency of 33.2 THz, outperforming existing phase‐change and microelectromechanical systems (MEMS) technologies. Using system‐level simulations, we demonstrate the robustness of this hardware through successful 1024‐quadrature amplitude modulation (1024‐QAM) demodulation, spectral analysis, and multiple‐input multiple‐output (MIMO) signal reconstruction, even when accounting for intrinsic device non‐idealities. This monolithic integration of high‐frequency switching and analog computing provides a scalable solution for energy‐efficient deployment of intelligent wireless systems.
