Abstract:
Ternary content addressable memory [TCAMs) are especially popular in network routers for
packet forwarding and classification, but they are also beneficial in a variety of other applications
that require high speed table lookup. They are used to implement lookup-table function in a single
clock cycle using dedicated comparison circuitry. Although it has many attractive features, higher
power consumption is very crucial drawbacks of TCAMs. Hence, a great amount of efforts have
to give to design T-CAMs without doing any compromise with its speed and voltage margin.
Match line sense amplifiers (MLSAs) consume a significant portion of the TCAM power for match
detection .This works compares circuit techniques for reducing TCAM power consumption
