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)
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).
