摘要：
Low-cost content-addressable memories (CAMs) are highly desirable for many applications where high-speed search is needed such as network routers and machine learning. We propose a low-power, compact, fast magnetic skyrmion-based ternary CAM (Sky-TCAM) cell design. Each cell comprises a 5T2R structure with five transistors and two magnetic tunnel junctions (MTJs). The search current polarity together with the stored bit can realize the XOR logic. When a mismatch happens, the skyrmion appears beneath one MTJ, leading to the discharge of the matchline (ML). While the search energy-delay-product (EDP) is comparable with that of non-volatile (NV) ternary CAMs (TCAMs), Sky-TCAM shows the lowest EDP of 8.74×10−25J⋅s among all TCAMs we compare. Our research shows that Sky-TCAM is promising for building low-power and low-latency computation applications.
