The Japan Science Technology Agency (JST) decided to invest in TopoLogic Inc. (CEO Taiki Sato, Headquarters in Tokyo) under the Support Program of Capital Contribution to Early-Stage Companies (SUCCESS).

TopoLogic is a startup based on the University of Tokyo that aims to socially implement topological materials. The electronic band structure of topological materials is completely different from that of conventional materials, leading to phenomena not seen in typical materials such as insulators, conductors (metals), and semiconductors. TopoLogic aims to develop a magnetoresistive random access memory (MRAM) using topological materials. MRAM is expected to be the future universal memory because it can reduce the power consumption to less than one tenth compared to the conventional memory, enabling reading and writing with high speed. Additionally, the company plans to design, develop, and demonstrate prototype chips by the end of 2025.

Furthermore, TopoLogic has been developing heat flux sensors that apply the characteristics of topological materials in collaboration with a wide range of companies.

Based on the research results of the Strategic Basic Research Programs CREST “Creation of Core Technology based on Topological Materials Science for Innovative Devices” (Research Director Satoru Nakatsuji, Professor of the University of Tokyo, 2018–2024) and JST-Mirai Program, Large Scale Type, “Innovation of Photoelectric Technologies using Spintronics” (Program Manager, Satoru Nakatsuji, Professor of the University of Tokyo, 2020–2030), TopoLogic, established in July 2021, has been advancing further research.
