What is it?

Any Electrical Engineering student is familiar with the fundamental passive circuit elements: the resistor, the capacitor and the inductor.

However, in 1971 Leon Chua (a Professor from UC Berkley) reasoned from symmetry arguments that there should be a fourth fundamental element, which he called a memristor (short for memory resistor).

Although he showed that such an element has many interesting and valuable circuit properties, until 2008 no one has presented either a useful physical model or an example of a memristor.

In 2008 HP (Hewlett-Packard) Labs announced that they succeeded to fabricate the missing memristor. Since then the interest in this device and its applications is rising and several more memristors were "found" (including RRAM, STT-MRAM, Phase-Change Memory, and spintronics).

The memristor may allow extension of Moore's Law for a few more years.

Memory can be implemented in all levels (cache, main memory and storage) with memristor-based memory and those applications can solve the current leakage problem and be the next generation nonvolatile memory.

There are many other potential applications with memristors including artificial intelligence, analog computing and brain-like circuits, detector of pollution in mobile devices, new approaches for logic and much more.

The memristor and memristive systems research is developing in a fast pace. In the coming graph you can see how fast it is in terms of the number of related published papers each year (according to Google Scholar, updated in 4/08/2013).

My Research about Memristor-based Circuits and Architectures

I am working on memristor-based applications both at circuit and architecture levels.

Right now I am working on several projects - memristor modeling, memristor-based logic design, and computer architecture in the memristor era (Memory-Intensive Computing).

We organized a workshop on memristors on 7th March, 2012 at the Technion. The program and the presentations can be found here. I talked about "Memristor-based Logic Circuit Design." (my talk). All the lectures are in YouTube.
