SAN JOSE, Calif.--(BUSINESS WIRE)--June 1, 2004

Aggressive Growth of NSE Sales Into Routers, Switches

and Other Networking Infrastructure Equipment Push

Unit Shipments Past New Milestone

Cypress Semiconductor Corporation (NYSE:CY), a market leader in NSEs, today announced that they have reached another milestone -- over 2.5 million network search engine (NSE) devices shipped. This announcement comes after the company reported an astounding 140% growth in NSE sales for 2003.

The recent shipment milestone and revenue stream increase is attributed to the proliferation of Cypress NSEs into a wide variety of diverse networking applications including traditional enterprise switching and core/edge routers as well as new applications including storage switches, security, wireless infrastructure and access systems (CMTS/DSLAM). Cypress's NSEs are being selected by major original equipment manufacturers (OEMs) to address performance, price and density requirements of these specific applications.

"Cypress is dedicated to providing a broad NSE portfolio and robust search system solution for all wire speed systems," said Gahan Richardson, Sr. Marketing Manager of the Network Search Engine Business Unit, "This latest shipment milestone further demonstrates the wide adoption of Cypress NSEs into evolving markets."

Cypress's Network Search Engines

Cypress's comprehensive NSE portfolio has been adopted by leading router, L2/3 switch, CMTS, DSLAM and storage area network manufacturers. As a result, in 2003 Cypress more than doubled its NSE market share and was recognized as the "big winner" in NSEs by a leading analyst firm.

The Ayama 10000 family of NSEs maintains the Cypress lead in the commercial TCAM market by extending the density and speed of the NSE70000 family: density options of 4-Mbit, 9-Mbit and 18-Mbit with speeds up to 266 MSPS. In addition, the Ayama 10000 family addresses system's power and latency concerns with differentiated features such as Mini-Key(TM) power management and Soft Priority(TM) table management. Mini-Key power management reduces power by engaging only the portion of the NSE array that contains entries of interest, thereby reducing power consumption by as much as 70%. Soft Priority table management enables dynamic prioritization of entries for longest prefix match (LPM) in Layer 3 forwarding applications, eliminating the latency associated with routing table updates.

Building on the Ayama 10000 family, the Ayama 20000 NSE is a high-performance TCAM-based network search engine that seamlessly connects to the Network Processing Forum (NPF) approved LA-1 interface-based commercial NPUs. The Ayama 20000 NSE has several key features such as two LA-1 ports for ingress/egress database sharing, automatic address generation for associated data, support for aging, and patent-pending dynamic power management. The Ayama 20000 NSE is available in 9-Mbit and 18-Mbit densities; at 266-million searches per second (MSPS) it is the highest-performance LA-1 based NSE in the market.

In addition to TCAM-based solutions, Cypress is the only vendor to also offer an Algorithmic SRAM-based forwarding search engine. The Sahasra(TM) 50000 NSE is a family of algorithmic search engines optimized for large forwarding tables in applications such as virtual router forwarding (VRF) and virtual private network (VPNs) that need greater than one-million table entries. The Sahasra NSE family can achieve 250 MSPS, at a fraction of the power and cost of existing TCAM-based search solutions.

These differentiated NSE products and advanced features are unmatched by any other vendors. This complete portfolio has lead to the strongest growth and continues to demonstrate Cypress Semiconductor as the volume leader in NSEs.
