TY - JOUR AU - Kang, Jinfeng AB - In this article, the design of a novel 3D-NAND-based content addressable memory (CAM) consisting of two flash transistors with ultra-high density and low power consumption is proposed for data-intensive computing. Hewlett simulation program with integrated circuit emphasis (HSPICE) of a 3D-NAND-based CAM array is performed to study the functionality and properties of the presented CAM design, and the results indicate that the energy consumption is 0.196 fJ/bit/search. The cell density of a 16-layer 3D-NAND flash is 157 times higher than CAMs based on conventional static random access memory. Furthermore, to exploit the multibit storage property of 3D-NAND flash, we also propose a multilevel CAM design, which significantly boosts the cell density and expands the functionality. As a proof-of-concept illustration, we take a 4-level CAM to successfully implement the search operation. Furthermore, the impacts of 3D-NAND layers and parasitic effects on the performance of the proposed CAM design are also discussed.
