Is the Memristor the Key to the Positronic Brain
Every student of electronics learns that every circuit no matter how complex is made up of only three fundamental types of components. Resistors, Capacitors, and Inductors.
In 1971 while studying equations that linked these three fundamental elements together Prof. Leon Chua of the Electrical Engineering Department of UC Berkeley published a paper in which he predicted a fourth element would be found. “Memristor – The missing circuit element.” IEEE Trans. Circuit Theory CT-18, 507-519 (1971).
Now almost 40 years later this prediction has come true. Scientists at Hewlitt Packard have learned how to build memristors. So will all the electronic books need to be re-written. I guess, although there is a lot of controversy over whether or not the memristor is indeed a fourth basic element..
Memristor is short for Memory Resistor, it is a passive device in which the resistance can be varied in circuit. What makes the memristor different from other types of variable resisitors is that a memristor will retain its last set resistance even when the device is turned off.
Applications for memristors are computer memory that retains its state when turned off, so no more boot up required, push the power button and instantly the computer is up and running. Memristors all will greatly simplify construction of artificial synanpses and so by extension artificial brains.
