Implementations of a resistive random access memory may include a bottom electrode; a helical layer of hafnium oxide coupled to the bottom electrode; an isolation layer coupled to the helical layer; and a top electrode coupled to the isolation layer.

Flexible memory systems and related methods

Implementations of light filters for use in cryptographic operations may include: a substrate having at least a first side and a second side, the first side opposing the second side, the substrate including one of a translucent, a transparent, and a semi-transparent material, and any combination thereof; and one or more layers of microscopic structures coupled to one of the first side, the second side, and both the first side and the second side of the substrate, the microscopic structures each containing one or more structural elements configured to interact with light. The microscopic structures may be configured to collectively form a unique light pattern on a detector optically coupled with the light filter. The unique pattern may be configured to be used to form a challenge-response pair (CRP) and the CRP is configured to be used in cryptographic operations to authenticate an electronic device associated with the light filter.
