PROBLEM TO BE SOLVED: To reduce a bit cost of a CAM cell by decreasing the number of elements and dispersing with wiring supplying fixed voltage. SOLUTION: This device has a first write-in transistor Mw1 of which a gate is connected to a word line WL and a drain is connected to a first bit line BL, a second bit line /BL of which a gate is connected to the word line WL and a drain is connected to a second bit line /BL, a first retrieving transistor Ms1 connected between the first bit line BL and a match line ML and of which a gate is connected to a storage node SN1, a second retrieving transistor Ms2 connected between the second bit line /BL and a match line ML and of which a gate is connected to a storage node SN2, and first and second capacitors C1, C2 connected between gates of the first and the second retrieving transistors Ms1, Ms2 and the match line ML. |
