Emerging spin orbit torque (SOT) promises to achieve high-speed write operation for magnetoresistive random access memory (MRAM) since it can eliminate the incubation delay of the conventional spin transfer torque (STT). Such a speed improvement allows the MRAM to be used as low-level cache in the computer architecture. Among various SOT technologies, spin-Hall-assisted STT is a potential candidate thanks to its magnetic-field-free benefit. In this work, we evaluate the potential of the spin-Hall-assisted STT-MRAM in the cache replacement. Firstly, the bit-cell parameters are obtained from the circuit-level simulation. Then, the cache evaluation and system-level simulation are performed with NVSim and Gem5 simulators. Simulation results validate the advantage of the spin-Hall-assisted STT in the write speed and energy. Moreover, for the large capacity (about >2 MB), the spin-Hall-assisted STT-MRAM is a competitive candidate for replacing the conventional SRAM-based cache. |
