Center node: "analog content addressable memories with memristors"
  Abstract: A content addressable memory (CAM) is a special form of memory that compares an input search word against all rows of stored words in an array in a highly parallel manner. While supplying a very powerful functionality for many applications in pattern matching and search, CAMs suffer from large area, cost and power consumption, limiting their use. Past improvements have been realized by using non-volatile memristors to replace the static-random-access memory in conventional designs, but employ similar schemes based only on binary or ternary states for storage and search. We propose a new analog CAM concept and circuit to overcome these limitations by utilizing the analog conductance tunability of memristors. Our analog CAM stores data within the programmable conductance and can take as input either analog or digital search values. Experimental demonstrations and scaled simulations validated the concept and performance, with analysis showing that our analog CAM can reduce area and power consumption (37$\times$) compared to a digital version. The analog processing nature enables the acceleration of existing CAM applications, but also new computing application areas including fuzzy logic, probabilistic computing, and decision trees.
