While AMD's shares are rising another one of the key people at AMD steped down from his position. After the recent "departure" of CEO Dirk Meyer, COO Robert J. Rivet followed suit.

Mr. Robert J. Rivet, a Motorola veteran since 1976, has been with AMD since 2000 as a senior vice president and chief financial officer. He was promoted to COO in 2002 but has now left the company according to an 8-K filling made by company on February 8th.

Biography details for Mr. Robert J. Rivet are already down at AMD's website, so we'll wait to see who will take his place. We can't help but wonder who will be next one as it looks like AMD is on a roll.
