Claim 0:
1. An analog content-address memory (analog CAM) having approximation matching, comprising:
an inputting circuit, configured to provide an inputting data;
at least one analog CAM cell, connected to the inputting circuit and receive the inputting data, wherein the analog CAM cell has a mild swing match curve whose highest point corresponds to a stored data, wherein a segment from the highest point of the mild swing match curve to a lowest point of the mild swing match curve corresponds to at least three data values; and
an outputting circuit, connected to the analog CAM cell and receive a match signal from the analog CAM cell, wherein the outputting circuit outputs a match approximation level according to the match signal.
