The term ‘memristor circuits’ might sound new to many, but it is a word that will certainly create a buzz in the world of technology in the future. It is undoubtedly the ‘Next Big Thing’! Memristor, a technology that is expected to be much cheaper and faster than flash storage, is a microscopic component that has a unique ability to remember electrical states even when in a ‘turned off’ mode.
Although the concept of these microscopic circuits was theorized in the year 1971 by UC Berkeley researcher Leon Chua, it is only recently that this technology has been created in labs. Hewlett-Packard (HP) is the first to have built it. In fact, it has already started to revolutionize almost everything we are aware of in the field of computing and is expected to supersede RAM, flash memory, and hard drives within a decade.
Among all the amazing technological innovations, ranging from the ones that promise to make paperless offices a reality to those that deliver wireless power, a memristor circuit is one such incredible innovation that claims to send shock waves through the computing world by turning your modest Personal Computer (PC) into a far different beast.
Memristor is the fourth type of circuit component after resistors, inductors, and capacitors. As its name suggests, it can not only remember the amount of current that passes through it, but can also alternate it. Allowing greater memory densities, these revolutionary one-element circuits have the potential to replace RAM chips. In other words, after you turn off your PC, it will remember exactly what it was doing when you turn it back on, and return to work instantly. Thus, lowering of cost and consolidating of components might lead to affordable, solid-state computers that can fit in our pockets and run many times faster than today’s computers.
Although HP’s goal is to offer memristor circuits in the market by 2012, it might take several years before we can actually experience the era of memristor-based analog computers.
