Summary Box: Calif. jury decides vs. Rambus

THE DECISION: A California jury says chip-makers Micron Technology Inc. and Hynix Semiconductor Inc. didn’t conspire to fix prices of memory chips in order to make products designed by Rambus Inc. more expensive.

BILLIONS DENIED: Rambus had been seeking about $4 billion in damages. If the jury had found in favor of the company, the award would have tripled under California law.

MARKET REACTION: Rambus’ stock sank 61 percent Wednesday after losing its 7-year-old antitrust case in California Superior Court in San Francisco. Micron’s stock rose 23 percent.
