SOI, FD vs. PD

I don't care about existing NovaThor products, I care about FD-SOI. Stop changing the subject.

I'm glad you now have a more realistic understanding of FinFETs and FD-SOI.

It's a fiction until it is in production. Which is a year off. At that point in time, it will become obvious exactly what kind of performance FD-SOI delivers. It's low performance and low power.

The variable costs of FD-SOI are higher, but the NRE is probably lower. That's a good trade-off for a company like STE or STM, both of which aren't doing particularly well.

Intel has a history of making aggressive claims about process technology and then delivering. They nailed high-k/metal gates, they nailed FinFETs. In each case, they got significant performance and power benefits.

That's not hype, that's doing good work.

Intel likes to brag about its process technology, but that's quite different than marketing and trying to sell it to other people.

More to the point, Intel doesn't need to convince anyone else it's a good idea.

TSMC and Intel are the two largest manufacturers of digital logic. They both came to the same conclusion, that bulk FinFETs are the right technology for the future. Intel at 22nm, TSMC at 14nm.

So like it or not, the majority of the industry will be using FinFETs.

>And the last and best about ZRAM.. it was not on SOI it was >on bulk and on some exotic FinFET form..

ZRAM was on SOI and it was a failure. It was bad technology.

ZRAM on bulk is also problematic, but it didn't come till much later.

If you look back in 2007, ZRAM was working on SOI. Go read those press releases.

>Perhaps too expensive to manufacture now.. but not without >future... that is why Micron bought it.

So when do you think the first ZRAM products will come out?

My guess: Not for at least 10 years, and more likely never.
