- Rambus and Juniper -
Juniper is incorporating Rambus RDRAM memory for use with the port cards in one of their newest routers, the T640. More on this product here:
Juniper T640. RDRAM is used as the main memory in the routing node.

Scroll down to the fourth page of this PDF document to see how RDRAM is used: T640 System Architecture Overview. This appears to be, by far, Rambus` largest design win in the telecommunications market.
The T640 is Juniper`s current flagship product, and is capable of simultaneously supporting 32 OC-192 (10 gigabits/second) or 128 OC-48 (2.5 gigabits/second) port cards.
When taking this into account along with the integration of Juniper`s routing matrix technology, which allows multiple routers to be "clustered" so as to act like a single router, a case can be made that the T640 is, at present, the most advanced Internet routing platform in the world. Up until now, while DRAM has often been used on the port cards of low-end and mid-range switches and routers, such high-end devices have used DRAM only in conjunction with their central processors (the T640 uses SDRAM for this task).
For the dozens of port cards that carry out the actual data processing functions, SRAM has normally been the memory platform of choice. The T640 clearly marks a break with this tradition, and of the various DRAM technologies available to Juniper`s engineers when designing product, RDRAM was the one that they chose to opt for.
