The use of TCAM is growing with the expansion of internet
protocol for data driven by IoT applications
With port speeds exceeding 100Gbps, route lookups that are fundamental to all routers have relied on ternary content addressable memories (TCAMs) to provide a lookup response within a clock cycle. However, TCAMs in discrete form are expensive, consume a lot of power, compete for precious real estate on the printed circuit board (PCB), and often lack required flexibility. Embedding a TCAM block along with the rest of the system in a single device should overcome these disadvantages. This paper provides
an overview of the advantages of embedded TCAMs and describes several applications that would particularly benefit from embedded TCAM technology.
