The current is not the 200MA/cm2 in the 16nm feature. It is the 600uA. I assume they meaured roughly 600uA and devide by 16nm x 16nm area to get to 200MA/cm2. Reverse thinking: if you bundle in parallel a bunch of those 16nm features to form an array that has an area of 1cm2, than you will need 200 MA to program them all together. So in other words, the concern in the article is that 600uA is large for 16nm node. Therefore the viability of PCM for memory is in question!

OK now I get it. Thanks for the clarification. It's still hard to see where all the current will come through. There's only so much metal in the stack and you still have contacts and vias which not support such current densities. It's not just at the transistor/channel level where the current density issues will occur.

Ooops typo: meant ...one would get a current of 600mA... Sorry!

A/cm2 unit represents current density which is standard in semiconductor devices. For instance, in the 200 MA/cm2 and 16nm node/size one would get a current of 600um for that given node (assuming a square 16x16 nm2), which cannot be easy to visualyze if compared to the "current" of another size.

Looks like memristor tech will win out

20 MA is 20 Mega Amperes. This kind of mistake in an electrical engineering publication is simply NOT ACCEPTABLE.
