A Memristor-CAM (Content Addressable Memory) Cell: New Design and Evaluation

Content addressable memory (CAM) is one kind of the associative memory; it can be used in several high-speed searching applications. In this paper, we propose a new CAM cell that employs memristors (memory resistor) as the storage element and the main part of the comparator. This presented new CAM cell involves two memristors; one is for saving the data as a storage element and the other one is used as an important part of the comparator instead of the conventional logic gate. Based on the unique characters of the memristor, we explore the new Memristor-CAM cell design to analyze the possibility to build memristor-based storage structures with lower power consumption to achieve the purpose of saving energy and decreasing the searching time.
