Oh that's a bit smaller than I thought for eDRAM, I guess it's been a while since I looked into it. I didn't think they had actually started making it at 40nm, http://am.renesas.com/products/soc/asic/cbic/ipcore/edram/ still lists 40nm as under development.

What? In 2009 NEC and TSMC already have eDRAM in 40nm.

The IBM POWER7 uses 45nm eDRAM and they already started to manufacture 32nm eDRAM (0.24mm2 per Mbit) in Feb, 2012.

Can't say I have followed eDRAM production at all so when I went to the site of the company that is providing the eDRAM and saw that they still listed 40nm as under development I just assumed that they hadn't ramped up on 40nm volume production yet. Oh well live and learn.
