MTJ-based nonvolatile logic LSI for ultra low-power and highly dependable computing

A 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, power and reliability wall on the present CMOS-only-based logic LSIs. Some concrete design examples based on the NV-LIM architecture using MTJ device are demonstrated and their usefulness is discussed in comparison with the corresponding CMOS-only-based realization.
