Which phenomenon allows non-volatile memory in magnetic RAM?

💡 Explanation

Domain wall pinning enables non-volatile memory because it obstructs boundary motion between magnetic domains, thereby retaining data; therefore spins remain aligned rather than freely rotating due to thermal effects under superparamagnetism.
