Challenge of MTJ-based nonvolatile logic-in-memory architecture for ultra low-power and highly dependable VLSI computing

Novel logic-LSI architecture, “nonvolatile logic-in-memory (NV-LIM) architecture,” where nonvolatile 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.
