Signal delay is proportional to the RC time constant "tau," wich his the product of R and C. Think about it, it takes time to charge a capacitor, right?  The more capacitance, the larger the charge time.

The 4Gb MRAM from SKHynix/Toshiba is impressive but the BER near ppm range is still too high to compete with DRAM, especially with the larger cell size.

No interconnect innovations at 10nm?

I doubt much of the interconnect innovations that Brain's talking about will make it into the 10nm node, because the IDF presentation from Bohr showed a low improvement in transistor delay (which was more than made up by the improvement in power). I am a bit confused as to what the benefit of air gaps exactly is. I understand it improves capacitance, which should improve power, but the article says air gaps help delay.
