GlobalFoundries Inc., also a chip manufacturer, says Ruiz will take a voluntary leave from his position as chairman before resigning officially Jan. 4.

The Wall Street Journal reported last week that Ruiz is the executive fingered by the Manhattan U.S. Attorney's Office for leaking insider information to Danielle Chiesi, one of six people arrested in the Galleon case.

Ruiz is not a defendant in the case. AMD has said it is reviewing the report but is not aware of any allegation of criminal misconduct by its current or former employees.
