<p>IBM researchers have discovered a materials breakthrough that could lead to processors that use less power and operate the way a human brain does.</p><p>Silicon-based processors rely on electronics and voltage being ushered through a channel. These semiconductors, which power PCs, tablets and smartphones today, were thought under Moore's Law to double performance every two years with lower costs and size. However, new manufacturing techniques will be needed as Moore's Law hits physical limits.</p><p>IBM's discovery, published in the latest edition of Science, flips the current semiconductor manufacturing process. In a nutshell, IBM scientists found a way to power chips with ionic currents, streams of charged molecules that operate in an "event driven" way like the human brain. These processors would likely ride shotgun with silicon-based chips.

"We think this could enable a new class of devices that operate on the flow of small ionic currents instead of electrons," he said. As a result, ionic current chips wouldn't have to be charged on and off like traditional silicon.</p><p><a href="http://www.zdnet.com/ibm-materials-breakthrough-could-lead-to-human-brain-like-chips-7000012866/">Keep reading...</a></p><p>Read also:</p><p><a href="http://news.cnet.com/8301-11386_3-57575567-76/with-a-drop-of-liquid-ibm-develops-a-new-microchip-switch/">With a drop of liquid, IBM develops a new microchip switch</a> (CNET)</p><p><a href="http://www.engadget.com/2013/03/21/ibm-turns-metal-oxides-into-non-volatile-chips-through-currents/">IBM turns metal oxides into non-volatile chips through liquid currents</a> (Engadget)</p><p><a href="http://gigaom.com/2013/03/21/ibm-rethinks-the-transistor-to-keep-scaling-compute-power/">IBM rethinks the transistor to keep scaling compute power</a> (GigaOM)</p><p>Explore: <a href="http://news.google.com/news/more?ncl=dgYBXgTLNHJP43M7Vx7Q9dRhqjHZM&ned=us">5 additional articles.</a></p>
