In this paper, we propose a power-efficient memory operation, selective match line precharge, based on an analysis of power consumption in ternary content-addressable memory (TCAM). A statistical study reveals that, on average, 58% of power dissipation related to the match line operation is saved by deactivating the unnecessary swing of match lines. The improvement has been simulated and proved using 180 nm CMOS technology.
