Demonstration of CAM and TCAM using phase change devices

We demonstrate novel designs for Content Addressable Memory (CAM) and Ternary CAM (TCAM) using Phase Change Memory (PCM) technology, which can potentially improve density and power consumption by >5X as compared with conventional SRAM based implementations. Using Monte-Carlo simulations, we also predict the desired characteristics of PCM devices for realizing large, high performance CAM/TCAM chips. © 2011 IEEE.
