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. 

• A logic circuit is a tenable application of memristor. These can be used in hybrid CMOS memristor circuit or as a standalone logic gate. The memristor use in Field Programmable Gate Arrays (FPGAs) as a configure switch and in connecting the logic gates of CMOS is noteworthy applications. These can be used in future to do digital logic with the aid of implication rather than NAND. 
• Memory is the supreme application of memristor as it holds a single bit of data in the dynamic random-access memory (DRAM) where the capacitors are restored by memristor. Similar to DRAM and static random-access memory (SRAM), this foam of memory has several advantages such as non-volatility, excellent scalability and no leakage power. In terms of scalability and speed, it is superior to flash memory. 
• The working of the memristor is almost similar to biological synapses. This function provides strong building blocks in a neuromorphic system where synapses and neurons are shaped as electronic structures. Such kind of memory has several other advantages when equating it to DRAM and SRAM. 
• Memristor is also appropriate for analogic filter application as well as for remote sensing and low power applications.
