Samsung talks about 20nm chips, tests in 2011

Moore's Law states that the density of a chip will double approximately every two years. Samsung has declared that the law is not slowing down to a halt for the company, disclosing details regarding the roll-out of 20nm process technology, which will enable the transistor count to roughly double yet again.
