报告摘要:An acronym for “memory resistor”, the memristor was first postulated in 1971 but did not see its light of day until only recently when HP published in the Journal NATURE a working titanium-dioxide memristor smaller in size than the smallest known virus. Since memristors can store information without a battery, this invention has generated immense worldwide attention in view of the economic impact of a disruptive technology that would replace flash memories, DRAMs, and hard drives – currently a 150 billion dollar industry. This lecture will give an elementary introduction on the memristor and reveals the origin of its magical “non-volatile” memory. It will also show why the memristor is the 4th basic circuit element, on par with the resistor, the inductor, and the capacitor.
It will also demonstrate that the significance of the memristor transcends economics by virtue of the recent discovery that both the “synapses” and the “axons” in our brain can be emulated by memristors. This fundamental result shows that it is impossible to build a brain-like computer without using memristors.
It follows that the memristor is the holygrail for building portable, low-power, and intelligent brain-like machines.
