Abstract
A CAM device includes a cell array including a plurality of CAM cells, a search line driving circuit connected to the cell array through a plurality of search lines, and a match line sensing circuit connected to the cell array through a plurality of match lines. Each of the CAM cells includes a first half CAM cell connected to a first match line and a second half CAM cell connected to a second match line different from the first match line. The first match line connected to the first half CAM cell is precharged in a first phase, and the second match line connected to the second half CAM cell is precharged in a second phase after the first phase. Thus, power consumption of the CAM device is reduced and delay is minimized.
