None of that is really relevant, because TSMC isn't in the business of making flash memory. The fab processes for logic and for flash memory are so different that there's no point to making comparisons between their respective nodes.
- bob1029 4y agoI don't know about "no point to making comparisons", but they are definitely different animals. When I worked at Samsung, flash & LSI were like 2 different companies. Lots of reuse at the systems engineering level though. At a certain point of abstraction you can't tell what is on the wafer anymore so you might as well track it in the same database.
- j_walter 4y agoCompletely different animals. I know that when TSMC has looked at acquiring used fabs before and in at least one case because the fab was DRAM it was more costly and time consuming to convert it to Logic fab than just building a whole new fab.
