3T2M canted-type x SOT-MRAM: Field-free, high-energy-efficiency, and high-read-margin memory toward cache applications

We propose a novel cell structure of spin–orbit torque (SOT) magnetic random-access memory (MRAM), which consists of three transistors and two canted-type x SOT magnetic tunnel junctions (3T2M) with opposite canting angle (+φ/-φ) on a shared heavy-metal, enabling a self-referencing scheme. Owing to...
