US Patent 11144214 Memory authentication

Apparatuses and methods related to memory authentication. Memory devices can be authenticated utilizing authentication codes. An authentication code can be generated based on information stored in a fuse array of the memory device. The authentication code can be stored in the memory device. The stored authentication code can be compared to a captured authentication code based on fuse array information broadcast to memory components of the memory device. The authenticity of the memory device can be determined based on the comparison and can result in placing the memory device in an unlocked state.
