That's a simple way to describe the disclosure of a new approach to computer chip design unveiled by IBM on Feb. 14 at the International Solid State Circuits Conference, a chip technology event in San Jose, Calif. IBM calls the approach eDRAM—the "e" stands for "embedded"—and says that combining the two types of chip onto a single piece of silicon will substantially improve processor performance. IBM plans to integrate this technique into its chips beginning in 2008.

Seems like if accessing memory is a problem, you would

1. put only one core on the chip and using the rest of the real estate for as much cache memory on the chip as possible.

2. use multiple layers of cost/speed tradeoff in memory:
   1. cache on chip
   2. SRAM chips
   3. DRAM
   4. flash memory or the new phase-change memory
   5. fast hard disk
   6. mass memory
