ONE OF THE MAJOR TECHNICAL HEADACHES facing chipmaker Intel is the leaking of current from inactive processors, company chairman Andy Grove told an audience at the International Electron Devices Meeting in San Francisco yesterday.
"Current is becoming a major factor and a limiter on how complex we can build chips," said Grove. He said the company engineers "just cant get rid of" power leakage.
The problem of leakage threatens the future validity of Moores Law. As chips become more powerful and draw more power, leakage tends to increase. The industry is used to power leakage rates of up to fifteen per cent, but chips constructed of increasing numbers of transistors can suffer power leakage of up to 40 per cent said Grove. In chips made up of a billion transistors may leak between 60 and 70 Watts of power, he warned. The power is largely dissipated as heat causing cooling problems for powerful chips.
