Abstract :

The growing demand for energy-efficient and high-performance computing systems has driven research toward non-volatile logic architectures. Conventional CMOSbased Arithmetic Logic Units (ALUs) suffer from high leakage power and volatility, leading to data loss during power interruptions. Magnetic devices, such as Magnetic Tunnel Junctions (MTJs), offer non-volatility, scalability, and low standby power. Majority logic has emerged as an efficient computation paradigm for implementing logic functions using magnetic devices. This work presents a fully non-volatile, reconfigurable magnetic Arithmetic Logic Unit based on majority logic. The proposed ALU integrates logic and memory, enabling in-memory computing. It supports multiple arithmetic and logical operations through dynamic reconfiguration. Majority gates are employed as fundamental building blocks to reduce transistor count. The architecture ensures low power consumption and high reliability. Non-volatility allows instant on/off ope
