Is the tech insights article new? The information seems disconnected with other reports. Example is actual definition on 19nm was changed by toshiba. Remember there is both an x and a y :-). Samsung nodes have been multiple between 26nm and 19nm (per techinsights).
Thanks for the story...this is a good list of what each memory vendor has been doing and are up to. A good summary. I wish I could have seen photos of where all those chips are being used (applications), rather than actual memory chips (which, you know, look kinda same)
