DescriptionCAM is widely used for associative search tasks due to the parallel pattern matching capability. There exists only little research on optimizing the design and energy overhead. In this paper, we propose a general compact and energy efficient CAM design that alleviates the design overhead by employing just one NVM device in the cell. We also propose an adaptive matchline precharge and discharge scheme that further optimizes the search energy overhead. We consider FeFETs as representative NVM, and present a CAM array design. Evaluation results suggest that our proposed CAM design achieve 6.64×/4.74×/9.14× better energy efficiency compared with CMOS/ReRAM/STT-MRAM approaches.
