Novel logic-LSI architecture, called “spintronicsbased nonvolatile logic-in-memory (NV-LIM) architecture,” where nonvolatile spintronic storage elements are distributed over a logic-circuit plane, is proposed as a promising candidate to overcome performance wall and power wall due to the present CMOS-only-based logic-LSIs. Some concrete design examples based on the NV-LIM architecture are demonstrated and their usefulness is discussed in comparison with the corresponding CMOS-only-based realization.
