In the field of electronics, we are familiar with three types of circuit components till now, i.e. capacitor, resistor, and inductor but in 1971, a researcher named Leon Chua gave a theory that could predict the possibility of the fourth component called memristor that would have the ability to measure the flow of current and after 37 years HP has built one.
A memristor is a circuit that has the ability to recall its state before the power cut and also how much current has passed through it and by alternating the current passed though it can become a circuit component with unique properties means it saves the state before the power cut and comes to that state after powering on the system which means it could replace flash memories in future.
Why do we need it?
In our present computer systems, we use RAM which is a volatile memory which means if the power goes off the data in the RAM gets erased and to solve this problem we use UPS but it also has its battery life and it is heavy and also it has its power backup of 15-30 min. Now in the place of RAM, if we use memristor, all these problems can be resolved and we don’t need any hardware like UPS and also it will be cheaper, efficient and faster than RAMs and flash memories and also with cost-effective, the system has the capability of consolidating the components that may lead to affordable and solid- state computers that may fit in our pocket and it would run hundred to thousand times faster than present day PCs.
- Cheaper and faster than flash memories
- It is non-volatile because it saves the state before the power cut
- It allows greater memory densities
- It is cost effective
- It consolidate components
If the memristor-based computer is made, then it will revolutionize the computer industry and it works on electrical states rather than working on 0 and 1 states on which today’s processor works. By working with a dynamic range of data states in an analog mode, memristor-based computers would be capable of far more complex tasks and operations than just shuttling around 0 and 1.
Researchers say that it will be implemented in the circuits immediately but it’s up to businesses to implement it commercially. It will also replace flash memories, DRAM and hard disks after 2014 and HP’s goal are to implement it by the latest.
