Reducing Energy in a Ternary Cam Using Charge Sharing Technique

Shilpa.C, Siddalingappa.C.Biradar

The ternary content addressable memory uses a match line sensing scheme. Here a selective precharge is combined with charge sharing technique to reduce the match line energy consumption. This technique improves speed. Unlike many existing scheme this scheme uses number of control signals need to be generated off-chip. A new match line sensing scheme for ternary content addressable memory (TCAM) is presented in this paper. A Match line sense amplifiers are used here in order to sense the match line which is high, when the data is matched. The Match line sense amplifier (MLSA) consists of Charging unit, Sensing unit and Differential amplifier. The differential amplifier compares the voltages and resulting the output depending on the data match and mismatch. The charge in one segment can shared with the next segment and hence reducing the energy consumption.
