Abstract

We have systematically investigated the reliability performance of spin-orbit torque (SOT) magnetic random access memory (MRAM) devices, including electromigration (EM), stress migration (SM), endurance and data retention. The results show that the SOT-MRAM devices pass the EM requirement over 10 years lifetime under the operation condition, and pass the SM requirement over 1000 hours baking at 175°C. Moreover, high endurance close to 1014 cycles and robust data retention over 10 years storage time were demonstrated for the same SOT-MRAM devices. This full characterization fills the blank of SOT-MRAM reliability research and would contribute to the commercialization of the SOT-MRAM.
