File information
Description	An image of a circuit with 17 memristors captured by an atomic force microscope. Each memristor is composed of two layers of titanium dioxide connected by wire. As electrical current is applied to one layer, the small signal resistance of the other layer is changed, which may in turn be used as a method to register data.^[1]

Fair use rationale for use in article Memristor

The image is of a historical scientific discovery
The image is of a low resolution (358 × 341 pixels)
The image provides a significant level of educational value to the article
The image is presumably covered by fair-use doctrine of U.S. copyright law, and in addition, appears to satisfy WP:NONFREE 2.1.3 #8
No free alternative currently exists

Non-free media information and use rationale true for Memristor
Description	Atomic Force Microscope image of a Memristor circuit array

Article	Memristor
Portion used	Full
Low resolution?	Sufficient to depict the subject, but no more.
Purpose of use	Illustrate the first known image of the Memristor test circuits
Replaceable?	No. Naturally, being an historical test circuit, even if a subsequent memristor were to be photographed it would not be equivalent to this image.
Other information	Intermediate source IEEE Spectrum
