Will Intel get back into the business of selling computer memory? It might, if one of the ideas in a recent chip prototype moves into manufacturing. On Tuesday, 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, Intel CTO Justin Rattner told News.com in an interview during the Intel Developer Forum. TSV could be used in a variety of chips, not just the 80-core monster. As a result, computer makers, when building a system, would get their memory when they bought their processors from Intel.
