Booze-sniffing electronic nose showcases 3D nanosystems [News]

You'd think computers spend most of their time and energy doing...well, computation. But that's not the case: About 90 percent of a computer's execution time and electrical energy is spent transferring data between processing and memory, says Subhasish Mitra, a computer scientist at Stanford University. Even if Moore's Law continued indefinitely, computers would still be limited by this memory bottleneck.
