Rambus Inc.
2465 Latham Street
Mountain View, CA 94040
tel: +1-650-944-8000
fax: +1-650-944-8080 USA Japan
Rambus Inc. [Nasdaq:RMBS] develops and licenses scalable bandwidth, chip-to-chip interface technologies that enables semiconductor memory devices and ASICs to keep pace with faster generations of processors and controllers. Rambus technology is incorporated onto dynamic-random-access-memory (DRAM) chips and the logic devices that control them to deliver more than ten times the performance of conventional DRAMs. A single Rambus(R) DRAM device, referred to as an RDRAM(R) device, transfers data at speeds up to 800MHz and beyond over the Rambus Channel to Rambus-compatible ICs.
Rambus chip connection technology is an open standard, accessible to all semiconductor companies. Rambus provides licensees with a full range of design, documentation and system-engineering services. In exchange, IC companies pay an up-front license fee and royalties. System companies buy Rambus-compatible ICs from licensed semiconductor companies; they do not pay separate royalties or license fees for using Rambus technology.
The high-bandwidth, low pin-count Rambus interface has a major impact on improving the price/performance and reducing the size of a broad range of systems from desktop computers to portables to communications systems to multimedia and consumer digital video products. Rambus Inc.'s unique technology uses standard CMOS processes, low cost IC packaging, and standard printed circuit board technologies to deliver the highest performance at a low cost.
2002/Sean: They have now diversified and in additon to their core memory business they are also designing serial link system platform / high-speed interconnects

The RC8650 voice synthesizer chip set is the latest creation from RC Systems. Our 16+ years experience in providing leading edge text to speech solutions has been integrated into silicon, now available in an easy to use chip set. You'll be amazed at the amount of functionality and versatility that we've built into these devices: unlimited vocabulary, on-the-fly voice control, tone generation, recorded voice playback, addressable voice channels, multiple input and output protocols... the list goes on.
Thought that a PC was the only way to generate speech from text? The RC8650 enables you to add text to speech capability to virtually any embedded system, quickly and painlessly, without a PC and virtually no overhead. You can send text messages to the RC8650 via an asynchronous serial port, printer port, or SRAM-like microprocessor interface. The audio output is delivered as either an analog signal or digital audio, if you need to do further processing of the audio stream. All the RC8650 asks for is 17 mA of operating current (5 V) to keep it happy, or only 2 uA when you're not using it. Think a PC would ask so little?

(1987: Founded. 1989: Acquired CMOS 4000 family from Allegro. 1991: Launched CMOS Analog/Digital Mixed Mode IC design group. 1993: Started providing complete solutions from production to volume delivery.)
