The shortfall is partly due to the "competitive and challenging" flash memory market, AMD said Monday. The company now expects operating income will be "down significantly" from third-quarter operating income of $68.4 million but that sales will be "up slightly" from the $1.24 billion in the third quarter.
"In a competitive and challenging NOR Flash memory market, the Memory Group is anticipated to have lower fourth-quarter sales and an operating loss," the company said in a statement.
