i guess this is meant for my post. do you understand what a metal only change is (as opposed to base change)? what makes you think that it means another level of metal or that it is a simple spin ?


I understand, I've been involved in dozens of minor and major steppings in 11+ years of making chips, and in all that time, every single metal layer change was done to improve speed paths or bin splits, or chip unit layout optimization. Just like intel's recently reported goals for going to 8 metal layers attested to. I have never seen changing chip functional charateristics as the goal, or the result, of metal layer changes, though, I don't have any experience with on die memory controllers specifically.
