It was less than 24 hours ago since the last post echoing an article on the NYT on memristors, and two more articles have appeared on both the NYT and CNN with the reports of the announcement, made on Tuesday by HP, that it would commercialize a new computer memory technology with Hynix, the South Korean chip maker.

Note: This posting summarizes some arguments I presented at the 2010 IEEE Symposium on Circuits and Systems. The complete presentation is available at this link.

Much of the recent interest in HP’s finding the “missing” memristor has been based on the presumption that it is correctly interpreted as the “4^th fundamental circuit element” after the resistor, capacitor, and inductor. The original argument from Leon Chua was that there were four ways to link the variables of charge and current to the variables of flux-linkage and voltage. The resistor, capacitor, and inductor represent three ways to link these variables while the memristor was postulated as representing the “missing” link connecting charge and flux-linkage. This may seem like a reasonable argument at first glance but it is not without flaws. Read the rest of this entry »

Dr. Snider and his colleagues at HP have built an integrated hybrid circuit with both transistors and memristors. Memristor crossbars are a very promising technology that can ultimately lead to building very dense hybrid chips, several times denser than synapses in the human cortex. Also, memristors have shown the potential to mimic the learning functions of synapses in neural networks. Memristors will the key technology that HP and its academic partner, Boston University, will leverage in the SyNAPSE grant.
