Abstract :
A string search engine for real-time address filtering (SSEAF) LSI is developed for 800-Mb/s local area networks (LANs). The SSEAF LSI contains a 16-kb (64-bit×256-word) content-addressable memory (CAM) which can store 256 workstation addresses. Simultaneously carried out within 80 ns in the CAM are both a comparison of a 64-bit destination address in an incoming data bucket with 256 stored addresses and the generation of any matched addresses. About 243 K MOSFETs are integrated on an 8.36-mm×8.5-mm chip using a double-metal 1.3-μm CMOS fabrication process
