Friday's Tech Winners & Losers

Shares of Saifun Semiconductors(SFUN Quote) were among technology's losers Friday, tumbled 27% after the company said that a big customer plans to scale back its nitride read-only memory business.

Saifun does not expect to receive any license or services fee from the customer, Qimonda(QI Quote), after the fourth quarter. Qimonda, which is a unit of Infineon(IFX Quote), had been a significant customer of Saifun's IP and design services.

Saifun said it will license NROM technology to Qimonda on a limited basis, resulting in only limited royalties. Although Saifun doesn't expect Qimonda's move to hurt it during the third quarter, Saifun does expect an impact beginning in the fourth quarter. Shares were trading down $7.76 to $21.32.

Shares of MSC.Software(MSCS Quote) plunged 14% after the software company projected third-quarter revenue well below Wall Street's forecast. The company estimated revenue of $58 million to $60 million and said it may record a "small" loss for the period. Analysts polled by Thomson First Call project a profit of 17 cents a share on revenue of $74.1 million. During the year-earlier period, the company reported revenue of $75.6 million.

"We believe that the third quarter financial results reflect the challenges associated with the transition of selling enterprise simulation solutions," MSC.Software said. "These challenges result in delayed purchase decisions on the part of our major customers, longer approval processes within their organizations and the lengthening of sales cycles." Shares recently were down $2.15 to $13.55.
