Replacing that with eDRAM cells taking up just one-third as much space will allow chip designers to build smaller chips and reduce the "run lengths" -- the length of wire that data must travel as it commutes around the chip, said John Barth, senior technology staff member and chief of eDRAM architecture at IBM.

IBM has used eDRAM in its chips for the BlueGene supercomputer, but those PowerPC processors use moderately performing, bulk-technology DRAM, which is far slower than SRAM.To create the new design, IBM will add a high-speed type of DRAM to its current silicon-on-insulator architecture.

"This DRAM now is almost as fast as SRAM.It may not be as fast at the micro level, but when you get down to 45nm, it will be faster at the system level.Its going to just blow the doors off," Barth said.

Elsewhere, an evening panel on memory evolution, organized by John Barth of IBM Microelectronics, will serve as a reminder of which memory technologies didn't work, which were successful and which came in between.

What do other nations expect of their students? What do high performance workplaces expect of new employees? What do universities expect? asked John Barth, a Goals Panel staff member.We can take much of the information available now and synthesize it so state policymakers and school districts can get a clearer picture of world class' academic standards that can help them set expectations for their own students and schools..

The Panel also will consider creating a resource group that would work on assessments and measuring student achievements.The group would examine the technical issues surrounding assessments and data collection, while providing information to policymakers and the public on the importance of assessments.
