SYMBOL OF
MEMRISTOR
Memristor is contraction of memory resistor.
It stores data by maintaining a particular
physical state, or orientation of atoms.
Resistance depends on magnitude and
polarity of the voltage applied.

It is the fourth passive element.
A type of electrical circuit connects capacitor, resistor, and
inductor.
Information storage device.
It remembers how much current has passed through it.
By changing the amount of current, resistance can be
changed.

Memristor = memory resistor
There are four fundamental circuit variables: electric
current, voltage, charge, and magnetic flux. For these
variables, we have resistors to relate current to voltage,
capacitors to relate voltage to charge, and inductors to
relate current to magnetic flux.

Each memristor is characterized by its memristance function
describing the charge-dependent rate of change of flux with
charge
From faraday's law of induction
If M(q(t)) is a constant, then we obtain OHM'S LAW

R(t) = V(t)/ I(t).

As with a pipe example
A resistor is like a pipe whose diameter is constant and
limits the water flow through it accordingly.

A memristor is like a pipe which has theproperty that if water flows through it in one
direction the diameter shrinks and if it flows
in the other direction it expands and once
water stops flowing through it, it remains thesame size until water starts flowing again.

Spintronics is the use of electron spin to store information.
Its all about the spin and charge of electron communicating
with each other.
Electrons can spin in two ways up or down
* each spin has different energy
* magnetic field affects the spins

Concept of Memristor by Leon Chua that was made practical
by Stan Williams (HP Labs) is a breakthrough in the field of
electronics
The current research work in HP labs shows that
It will enable very small,i.e. nanoscale devices to be made
without generating all the excess heat that scaling down
transistors is causing today and thus makes chips cheaper
It will eliminate RAM from computers
Eliminate rebooting function from computers
