Abstract

In this paper, we propose an energy efficient in-memory computing platform based on novel 4-terminal spin Hall effect-driven domain wall motion devices that could be employed as both non-volatile memory cell and in-memory logic unit. The proposed designs lead to unity of memory and logic. The device to architecture level simulation results show that, with 45% area increase, the proposed in-memory computing platform achieves the write energy ∼ 15.6 fJ/bit which is more than one order lower than that of standard 1-transistor 1-magnetic tunnel junction counterpart while keeping the identical 1ns writing speed. In addition, the proposed in-memory logic scheme improves the operating energy by 61.3% as compared with the conventional nonvolatile in-memory logic designs.
