XDR℠ Licensing Services

Rambus provides a number of licensing options to its technologies, including off-the-shelf interface* and full-custom interface** cells, all of which incorporate a number of our innovations and patents. Additionally, Rambus offers design kits for several of its interface technologies that enable customers to design the interfaces themselves. Our business model allows customers to choose the level of engineering services they need in order to incorporate Rambus technologies into their semiconductor or system designs.

• Licensees

* Off-the-shelf interface cells are Rambus and industry standard solutions ported to microfabrication processes from leading silicon foundries.
** Custom interface cells are solutions for integrated device manufacturers (IDM) with proprietary microfabrication processes, supporting customer-defined specifications or Rambus/industry standards.

For complete interface solutions, Rambus offers various families of interface products: Rambus serial links, XDR™ and RDRAM® memory interfaces, and FlexIO parallel interfaces. All licenses to our intellectual property cells include patent licenses to technologies for use within the specific cells.

For customers who prefer to design their own interface or who wish to incorporate Rambus innovations into their products, Rambus offers licenses to its patents.

XDR℠ Patent Licensing Services and Scope

Rambus is willing to license all its patents. In the most typical patent license, Rambus licensing rates are determined from a base price list. The list is subject to change, and is expected to change over time. Our practice has been to offer similarly situated licensees reasonably similar terms, with list prices that we believe to be consistent with industry norms for patents of similar importance. Typically, Rambus includes patent licenses with our interface cells and services.

XDR℠ Licensing Services and Practices

Rambus develops technologies that are broadly applicable to chip interface and system design. Some of these technologies will be included in implementing applications and systems for certain industry specifications and standards, including SDRAM, DDR SDRAM, and DDR2 SDRAM. Rambus is open to licensing its technologies for use in proprietary and industry standard applications, at reasonable rates, to either companies or individuals.
