Abstract
Due to emerging of hi-speed communication larger
TCAMs with higher speed is needed. A comparative analysis of
different Matchline sensing schemes in high speed Ternary
content addressable memory (TCAM) is presented in this paper.
With the conventional current race scheme, two different
methods of charge sharing matchline sensing schemes are being
analyzed. The power is distributed along the matchline by
dividing it and sharing charge. This two charge shared schemes
also improve search time and voltage margin. Simulations are
performed using 180nm 1.8V CMOS logic in HSPICE.
