5 Best Practices for Smartphone Support
To give an indication of Blue Gene's processing power, it would take the most powerful laptop computer 700 years to carry out the 200 billion billion calculations needed for the 50 different models developed by the researchers. IBM expects hafnium dioxide technology to reach products in 2008. While experiments with the material have been very promising, a thorough understanding of its nature will reduce the risk that it will have unforeseen consequences. Both IBM and Intel have announced they will use hafnium-based dielectrics in their 45nm chips. Intel is expected to beat IBM to the punch, beginning commercial production at the end of this year. Hafnium dioxide is one of the 'high-k' materials that can be used in thinner dielectric layers than the traditional silicon dioxide without allowing excessive current leakage and consequent heat generation.{moscomment} |
