SAN JOSE -- Tessera Technologies has filed a patent infringement suit against a pair of leading chip makers.

The filing, which came in U.S. District Court, charges Infineon Technologies and Micron Technology with illegal use of Tessera-patented designs for chip packages that contain memory and other semiconductor devices.

A Tessera spokesman said the company would provide no further details at this time.

Tessera licenses its package designs to other semiconductor makers.
