Designed for Multi-Layer Packet Processing in Networking Equipment such as Routers and Switches
-Deterministic, high-speed packet search up to 360 million searches per second (MSPS)/Table to enable 40G and beyond data transfer-
SAN JOSE, Calif.-Renesas Technology America, Inc., today introduced a high-performance TCAM (Ternary CAM)*1 Series, comprising a portfolio of TCAM memory products to enable high-speed packet processing for networking equipment such as routers and switches. The first product in the series is the R8A20410BG TCAM which has a capacity of 20 Mbits and delivers industry-leading high-speed search performance of up to 360 MSPS (mega-searches per second)/Table. Sample shipments will begin in December, 2009.
TCAM is a type of memory in which each memory cell can store three data states: 0, 1, and X ("Don''t Care"). It is suitable for applications such as networking equipment because it achieves deterministic, high-speed searches by using simultaneous parallel operation to compare data strings input from an external device with data strings stored in the memory and outputting the matches. As the use of networks, typified by the Internet, has spread widely in recent years, attention has focused on TCAMs as a key device for increasing the speed of packet forwarding (packet data transfers) by networking equipment by enabling high-speed lookup of destinations, etc., for large volumes of information during packet data transfers.
