Well this is something which I expect they will not sell to Lenovo…
IBM, one of the world's most advanced chip fabrication companies with the capability to manufacture on a 22nm node, is looking to sell this division. According to The Financial Times, via Ars Technica, the company selected Goldman Sachs to seek options. They are primarily looking for interested buyers but would also consider finding a business partner to offload the division into a joint venture.
The two initial candidates are GLOBALFOUNDRIES and TSMC.

IBM is not willing to get rid of its chip design ability. IBM creates many chips, often based on its own "Power Architecture". This trademark comes with their RISC-based instruction sets which rival ARM and x86. It forms the basis of the Xbox 360, the Cell processor found in the PS3 (and rarely elsewhere), and the last three Nintendo game consoles starting with the Gamecube.
Despite designing all of the above chips, only some were actually fabricated by IBM.
Personally, I am not sure how serious the earlier mentioned potential buyers are. It could have easily been someone who looked at the list of leading foundries and picked the top two. TSMC is not even a member of "the Common Platform" alliance, not to mention how small IBM is compared to them, so I cannot see much reason for TSMC to bother.
GLOBALFOUNDRIES is a different story, It would make sense for them to want that part of IBM (Josh notes they even share some resource centers). Still, the both of us wondered if they could afford the deal. ATIC, parent company of GLOBALFOUNDRIES, might be able to get the money from somewhere – but would they? They purchased Charter only just recently. Now, if they simply enter a partnership with IBM, that might be a different story than an outright purchase.
Fabrication is hard and expensive. Creating a foundry is about $10 billion, give or take a few billion depending on yield, and changing your equipment for new nodes or wafer sizes is not much cheaper. I can see IBM, a company that is increasing concerned with high profitability, wanting to let someone else deal with at least some of the volatility.
IBM has not commented on this rumor.
