The 9.4Mbits Ternary CAM device has been designed and fabricated. The performance of 200MHz/200MSPS(million searches per second) with 3.2W at 1.5V Vdd was achieved. Two new approaches were taken to achieve this performance. One is the Charge Injection Match Detect Circuits (CIMDC) for a very small swing voltage level (about 30QmV) of a match line and stable detection of it. The other is the improved Bank Selection Scheme (BSS) with the data-storing method in order to activate only the target bank where a match data is expected to be stored. The 200MSPS is 1.6 times faster and the 3.2W is almost 1/4 less power consumption compared with the conventional design.
