Scientists at IBM claimed today that it has cracked a materials conundrum that may well create a new class of memory and logic chips. The scientists discovered a way to operate chips using small ionic currents. That’s streams of charged atoms mimicking the way the human brain works. Moore’s Law is close to bust at the CMOS level, IBM thinks and low power and high performance semiconductors using different techniques will soon be needed. The IBM scientists have figured out that you can reversibly transform metal oxides between inslating and conductive states by inserting and removing oxygen ions through electric...
