Intel's Grove warns of the end of Moore's Law

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 can't 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.

While Intel is seeking ways to design chips with multiple cores with improved design and better insulators, Grove suggested that Moore Law regarding the doubling of transistor densities every couple of years will be redundant by the end of the decade. Chip makers will have to make more efficient use of the transistor in order to deliver ever increasing performance, he suggested.

Grove also addressed the diminished likelihood of an upturn in the chip industry in the near future. "Over the course of the past year (the industry) has been bounding along on the bottom," he said, but he warned that the threat of a "war" on Iraq doesn't bode well for the future employment rate in the US and a may spark a consequent "meltdown" in some South American economies.

The industry "was operating, in retrospect, way ahead of the underlying demand," he said in his keynote speech to the conference. "The excess of the latter 1990s was so much bigger than previous excesses," he confessed.

Grove also later warned that the trend of migrating chip manufacturing to far eastern fabs could shift the balance eastwards. "It is easy to project," he said, "that the interdependence becomes more one-sided, with an adverse impact on our educational system because so much of the university funding comes from industry. There is a spiral there in the wrong direction."

The trend also carried "huge" implications for defence, he warned. µ
