Now that the contact problem has been solved, scientist can start designing new components in which electronic and magnetic technology is combined.
Intel is also working on other ways to connect memory and processors more tightly.
Intel showed off an 80-core processor at its developer forum taking place in San Francisco this week and one of the prominent features of the chip is that each core is connected directly to a 256MB memory chip through a technology called Through Silicon Vias, or TSV.
The memory wedded to the processor cores could constitute the entire memory needed for a computer. The memory chips attached to the 80-core processor are SRAM, a relatively expensive memory that Intel still makes. The next step is to see how well DRAM works with TSV.
