The stock was last quoted at $5.73, down 2.4%, on volume of nearly 800,000, according to Nasdaq.com. Micron also gave a word of warning to investors about the coming jury decision in its antitrust case with Rambus ( RMBS), saying it can't "reasonably" estimate the range of possible losses from the suit. "An unfavorable outcome could have a material adverse impact on the company's results of operations for the fourth quarter of fiscal 2011," Micron said. Because of weak DRAM pricing, the company's gross margin dropped to 15% in the quarter from 22%. Micron said revenue from its NAND flash products rose 11% on a sequential basis as a 40% spike in volume offset a decline in average selling prices.
