An associative or content addressable memory (CAM) is a functional memory in which stored date are compared with an input date in parallel, and the contents and/or the addresses of any matches are then output. Such lookup capability is useful in many applications, including cache tag tables, image pattern recognition, artificial intelligence, packet switching in communication networks and hardware date base accelerators. In this paper, we propose a new high-density CAM with Hamming distance search functions. The CAM can compare stored date and an input date in parallel, and find stored date with Hamming distance within a certain range ("near match"). Also, the interrogation characteristics of the CAM are analyzed in detail. Furthermore, the results obtained from these analyses are fully confirmed by simulation using the circuit analysis program HSPICE.
