NEW YORK (TheStreet) -- The U.S. government has brought new securities-fraud charges in the ongoing insider-trading investigation.

This time, a woman named Winifred Jiau has been accused of selling insider information about technology companies

Marvell Technology

(MRVL) - Get Report

and

Nvidia

(NVDA) - Get Report

to hedge fund managers, a federal criminal complaint alleged. The complaint, filed in Manhattan federal court, was unsealed on Wednesday.

Jiau, who lives in the Silicon Valley town of Fremont, Calif., and who once worked as a contract employee for Marvell, was arrested by FBI agents at her home on Tuesday.

According to federal prosecutors, Jiau allegedly took more than $200,000 in exchange for inside information, including details about Marvell's not-yet-released financial results for the May and August quarters of 2008. Two hedge funds were alleged to be the recipients of the information. The complaint didn't name the funds.

Jiau reportedly has links to

, one of the expert-network firms that appears to be at the center of the federal insider-trading probe.
