And where is Global Foundries in all this ? Are they able to take advantage of the 28 nm demand yet ?

UMC would love to have a capacity problem right now. They are surely dumping their spend into 28nm primarily because that is where the new business is right now.

It begs the question, "Will UMC experience 'capacity issues' as they begin to ramp these design wins in a fashion similar to what TSMC saw?" Seems like perhaps UMC is spending more on 28nm now to address this potential issue in the same way TSMC upped their spend. Sure the processes are not all the same, but there will still be alot of similar issues.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
