Leon Chua proposed the existence of memristor in 1971
In 2008 a team lead by Stanley Williams created the first memristor

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.

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.

Memristor will change circuit design in the 21st century
