Spintronic memory has been considered as one of the most promising nonvolatile memory candidates to address the leakage power consumption in the post-Moore’s era. To date, the spintronic memory family has evolved in four-generation technology advancement, from toggle-MRAM (product in 2006), to STT-MRAM (product in 2012), to SHE-MRAM (intensive R&D today), and to VCMA-MRAM (intensive R&D today). The trend from field-controlled, to current-controlled, and to voltage-controlled devices, allows for more energy efficiency of the memory itself, because of the significant decrease of the ohmic loss or joule heating. Meanwhile, novel spintronic memory paradigms are emerging, e.g., racetrack memory, for ultra-high-density storage to replace HDD or SDD. On the other hand, from the architectural perspective, data transfer bandwidth and the related power consumption has become the most critical bottleneck in von-Neumann computing architecture, owing to the separation of the processor and the memory units and the performance mismatch between the two. Realization of the unity of computing and memory in the same chip has opened up a promising research direction of computing-in-memory (CIM). Spintronic memory could be a promising technology to implement the CIM paradigm, owing to its intrinsic processing capability. Lots of interests have been attracted and a number of attempts have been made in this field. In this talk, I will review the R&D evolution of spintronic memory: from memory to computing-in-memory. Particularly, I will introduce our recent work on advanced spintronic memories as well as CIM paradigms implemented within spintronic memories.
