Intel wants to discuss whether The Foundry Co. will constitute an AMD "subsidiary" as defined by the agreements. It is also concerned about how AMD's ATI acquisition may affect the agreements, according to the filing.

Rivet said on the conference call that Intel's letter is "in no way a condition" to AMD closing the Foundry deal, and that AMD expects to complete it on schedule if it gets the green light from its shareholders.

Spinning off its manufacturing business should improve AMD's financial position. Rivet said it will provide AMD with a cash injection of $700 million, and Meyer said AMD will be able to transfer debts from its fab in Dresden, Germany, to the The Foundry Co.
