Rambus' shares dived by almost a third yesterday after US reports claimed alleged illegal dealings could be used as evidence against the memory firm in its long-running legal battle over patents.
The company blasted the reports from brokerage group SG Cowen as inaccurate, saying no pre-trial ruling had been issued in the patent dispute case. Rambus spokeswoman Kristine Wiseman said, "No ruling has been issued yet."
However, additional reports also referred to a pre-trial ruling and claimed the decision could affect Rambus' royalty claims on synchronous dynamic random access memory (SDRAM) and double-date rate (DDR) memory.
The firm collects royalties from Samsung, Mitsubishi, NEC, Toshiba, Matsushita and Hitachi, and has pending lawsuits to collect royalties from Hyundai, Micron Technology and Infineon.
Shares in the SDRAM and DDR manufacturer fell $11.26 to close at $24.09 on the Nasdaq amid fears that such a ruling would bite into Rambus' royalties, a significant portion of its revenue. Stock is now at its lowest level since February 2000 and over $100 less than its June 2000 high of $127.
