They demonstrated a new memristor technology that can store up to 128 discernible memory states per switch, almost four times more than previously reported.
"Memristors are a key enabling technology for next-generation chips, which need to be highly reconfigurable yet affordable, scalable and energy-efficient.
"At the same time this technology is ideal for developing novel hardware that can learn and adapt autonomously, much like the human brain."
Traditionally, the processing of data in electronics has relied on integrated circuits (chips) featuring vast numbers of transistors – microscopic switches that control the flow of electrical current by turning it on or off.
Transistors have got smaller and smaller in order to meet the increasing demands of technology, but are now reaching their physical limit, with – for example – the processing chips that power smartphones containing an average of five billion transistors.
