Memristor is a passive non-Volatile electronic component, it possesses the property of both the memory and resistor. Memristor is considered as the fourth fundamental component after resistor, Capacitor and Inductor. The concept of memristor and memristance was first introduced by Prof. Leon Chua from university of California, Berkeley. A memristor a two terminal electrical component that can regulate the flow of electrical current in a circuit and can remember the amount of charge that have previously flowed through it.
When the current is stopped by turning of the applied voltage the component would remember the last resistance it had. Memristance is a phenomena wherein if the current flows in one direction through mermistor then its resistance increases and when the current flows in opposite direction its resistance decreases. The greatest advantage of the memristance over other conventional devices is that, the conventional devices uses 0 & 1 logic whereas memristor can use anything between 0 & 1 (i.e. 0.3, 0.5, 0.6 etc.). It provides greater reliability when power is interrupted. This system can be very useful in datacenters when the power is interrupted.
Hewlett Packard made the first Reliable discovery of memristance in 2008. Currently Hewlett Packard’s version of titanium Dioxide memristor is most commonly pursued in the market. The first commercial memristor was brought into market by Knowm Inc. with bidirectional incremental resistance change property.
There are various factors which are driving the growth of memristor Market. The key factor which would help to grow the memristor market is due to strong demand from smartphones, tablets, computer peripherals, and cloud vendors.
The other factors which could accelerate the growth of memristor market is due to its property of remembering its previously known resistance and it’s unique design. This helps to takes less time for booting up and it is faster than using transistor. As complex devices have more transitions, thus memristor can be a replacement of increasing number of transitions in a circuit. It provides flexibility of storing information, thus acting as a great threat to DRAM, NAND flash memory and hard drives market space.
Miniaturized design of memristors takes less space and consumes less voltage which can be used in programmable logic, signal processing processing and RFID’s. However, as they are still in the developing stage, there -can be many threats such as error rates, reliability, ease of programming etc. which can decline the memristor market. Also, companies such as Rambus, Panasonic & Crossbar are working on Resistive RAM Technologies which is can be an alternative to memristor.
The memristor market is segmented by type into the following categories: By type it is divided into titanium dioxide memristor, polymeric (ionic) memristor, ferroelectric memristor, resonant tunneling diode memristor, graphene oxide memristor, silicon oxide memristor. On the basis of memory size, the Memristor market can be divided into amount of memory size required in electronic devices into 4GB, 8GB, 16GB, 32GB, 64GB & more than 64GB. It can also be segmented on the basis of industry vertical into following segments: datacenters, computer peripherals, healthcare and telecommunications.
On the basis of Geography, the market can be subdivided in to North America, Europe, Asia Pacific, Middle East Africa and South America. North America can continue to dominate the memristor Market in the coming years. The North America and Europe are majorly leading the memristor market, as the developed countries here majorly invests into research and development. Asia can be their potential largest market, as the populated countries like India, China and Indonesia are the major consumers of electronic’s industry.
Key players in the Memristor market includes Hewlett-Packard, SanDisk, Knowm Inc., Crossbar Inc., SK Hynix, IBM, Samsung, Rambus, HRL Laboratories, Micron Technology, AMD Inc, Panasonic Corporation. Currently Hewlett Packard’s version of titanium Dioxide Memristor is most commonly pursued into the market .In order to gain a competitive advantage in the industry, these players are actively involved in researching, discovering and prototyping thousands of various types of memristors.
