In a highly technical conspiracy trial slated to go on for five months in San Francisco Superior Court, Rambus attorneys have a challenge ahead of them: keeping jurors awake.

The Sunnyvale-based technology licensing company is two weeks into its antitrust case against competitors Micron Technology Inc. and Hynix Semiconductor Inc., alleging that the two companies colluded to force Rambus Inc. and its proprietary high-speed computer memory technology, RDRAM, out of the market in 2000. Rambus is seeking billions in damages; last year, Samsung agreed to pay $900 million to settle similar allegations.
