Analogy Of Memristor
The diameter of pipe remains same when the current is switched off, until it is switched on again.
The pipe, when the current is switched on again, remembers what current has flowed through it.
Definition of Memristor
A memristor is a device whose resistance varies as a function of flux and current. This allows it to “remember” what has passed through the circuit.
Characterized by Memristance
Emergence Of Memristic Theory
Theory was developed in 1971 by Professor Leon Chua at University of California, Berkeley.
Found while exploring symmetry between the three fundamental passive linear circuit elements
In 2006, R.Stanley Williams developed practical model.
Memristic State
Found when researching ways to overcome nano-scale manufacturing issues.
Memristivity has an inverse square relationship with thickness of the material, so
smaller = better!
Nonvolatile state can be accomplished by memristors because their state is encoded by impedance (physically), not by voltage.
What Sets Memristor Apart ?
Conventional devices use only 0 and 1; Memristor can use anything between 0 and 1.
Faster than Flash memory.
Alloaw digital cameras to take pictures with no delay inbetween
Innovating nanotechnology due to the fact that it performs better the smaller it becomes.
Future Technological Significance
Being implemented to do neural computing. (post office, banks).
Pattern recognition and learning.
Crossbar latches to replace transistors.
New forms signal processing and control systems.
