Micron D9 and high voltage, electromigration effects

[Calmatory]

the cleaner the current the safer it is
vdmm voltage regurators play big role
keepin heat down important too

Obviously. But what I am after is the influence of electromigration in other ICs aswell, not jsut DRAM chips.

Are DRAM chips more vulnerable to damage caused by electromigration? If the required current is defined by the frequency, wouldn't these high clockspeeds(+4GHz 24/7 use) and thus high currents flowing trough CPUs kill them very quickly? Or are CPUs just much more resistant/durable by default currents and temperatures? Could have alot to do with manufacturing process and methods (high-k & metal gates etc.) used.
