"Sony is looking at ways to improve its chip operations but has reached no decision
, the company said Tuesday, denying Japanese media reports that it has a deal
to sell the business to Toshiba."
"Toshiba Corp. spokesman Keisuke Omori said nothing has been decided on such a deal
Can indicate that a) A deal has not been reached, and b) Sony is working on a deal to sell that fab.
As such Sony is simply denying that a deal has been reached, and not denying that a deal is in the works. Both uses while technically correct are not good uses of the word, as many people consider deny=never but in this usage it is not the case.
