The document discusses memristors, a type of semiconductor whose resistance varies with charge and flux, first proposed by Leon Chua in 1971 and later developed by Stanley Williams in 2008. Memristors offer advantages over conventional devices, including non-volatility, energy efficiency, greater data storage density, and the ability to operate quicker than flash memory. Their unique properties are set to revolutionize circuit design and technology in the 21st century.

9.  Would allow for a quicker boot up since information is not lost
when the device is turned off.
 Uses less energy and produces less heat.
 Eliminates the need to write computer programs that replicate small
parts of the brain.
 Density allows for more information to be stored.

10.  Conventional devices use only 0 and 1; Memristor can use
anything between 0 and 1.
 Faster than Flash memory.
• Allow digital cameras to take pictures with no delay in
between.
 Innovating nanotechnology due to the fact that it performs better
the smaller it becomes.

11.  Memristor will change circuit design in the 21st century

“It’s time to rewrite
all the EE textbooks”
