Abstract

Content addressable memory (CAM) integrated with non-volatile racetrack memory (RM) can perform the lookup function with a very fast speed. However, the bidirectional motion of domain walls (DWs) in the stripe-shaped RM based CAM will cause data overflow issue, resulting in larger physical size and lower performance. In this paper, a ring-shaped CAM based on spin orbit torque (SOT) driven chiral DW motions has been designed and simulated. Thanks to the circuit simplification and high efficiency of chiral DW motions, its area, energy consumption and operational speed can be greatly improved.
