Memristor (an amalgamation of memory and resistor) is passive non-linear two-terminal electronic components having a variable electrical resistance.
They are very much simpler than transistor and can use less energy. They can also change their resistance and recall their previous state that might contribute towards better-distributed memory and computing.
A transistor is the cornerstone of all the microchip technologies which has been miniaturized to nano-scale size and to accommodate billion on to a chip, yet it is a technology that exceeds its limits. The concept of memristors is providing a new opportunity for microelectronic design. They may provide more processing capacity packed in a smaller region with less resource usage. It is also expected that in future, it will allow application like the internet of things (IoT), radiation-resistant electronic and in smart medical devices. However, there are several applications of the memristor in the neuromorphic system, digital memory logic circuits and in a biological system.
