In 1971, Leon Chua was the first person to propose the memristor as the fourth fundamental two-terminal passive circuit element. Chua based his proposal on the symmetry of equations describing fundamental circuit elements. This device is distinguished by the fact that the voltage applied to its input might alter the value of its instantaneous resistance. The instantaneous resistance is a non-volatile quantity since it continues to exist in the circuit even when the voltage applied to the input is removed. During the next ten years, it is anticipated that there will be a physical limit placed on the size of nanoscale CMOS transistors. Creating novel nanoscale components with distinctive functions and dynamics is one of the long-term goals of the Beyond CMOS project. Memristive devices, spintronics, molecular electronics, quantum computers, and generic electronic components with unique state variables stored in resistance, photons, flux, and other things are some examples of these technologies. These research areas are not yet ready to be included into standard CMOS manufacturing practices as they are still in the early stages of development. It is necessary to research and create novel devices that are able to surpass typical similar CMOS implementations in order to accommodate this need. One example of this kind of gadget is the memristor. With the success of the memristor, Di Ventra, Pershin, and Chua expanded the concept of memory circuit components to capacitive and inductive systems, respectively, and invented the memcapacitor and the meminductor. Both of these inventions followed in the footsteps of the memristor. It is believed that a research team at Hewlett-Packard (HP) in California, led by Stanley Williams, was responsible for the creation of the world's first memristor in the year 2008.
