Description
Summary:A cell-based design flow for MTJ/MOS-hybrid logic circuits is presented towards the realization of practical-scale logic LSI based on nonvolatile logic-in-memory architecture. Newly-developed supplementary design tools including a precise MTJ device model enable to design MTJ/MOS-hybrid logic's intellectual properties (IPs) accurately. By the use of the IPs, various pattern layouts of the MOS and MTJ/MOS-hybrid logic-circuit cells can be automatically synthesized. The effectiveness of the proposed design flow is demonstrated through typical arithmetic-circuit design examples with a nonvolatile storage capability.
