Toru Masaoka
Chief Executive Officer

In recent development of semiconductor technology, there has been limits in achieving low power consumption and high-speed processing for LSI circuits, and there is a need for innovative technologies.
Center of Innovative Integrated Electronic Systems (CIES), Tohoku University,promotes Japanese-specific research and development aimed at open innovation, gathers market leaders in the semiconductor industry from around the world, and attempts the establishment and practical use of innovative fundamental technologies.
Specifically, we are focusing on technologies related to spintronics to achieve large-capacity, high-speed, high-reliability, Nonvolatile memory (STT-MRAM) and GaN-on-Si power electronics that contribute to of improvement of power efficiency of power devices, definitely hold the corner stone in building our future society.
Power Spin Inc. was launched as a Tohoku University-based startup company that aims to implementation the technologies that the above mentioned CIES has been creating in society.Through strong cooperation with Tohoku University, including CIES, we are able to have a competitive edge over other semiconductor companies, and we will create ultra-low-power industrial products by matching the core technology possessed by CIES to the customer’s specifications.We will develop the designing, and making prototypes, and licensing, and consulting service businesses as four pillars in order to be reflected in the commercialization of customers. In order to do so, we will gather young people, and maintain both flexible management and world-leading technology.
As a start up company from Tohoku University, we provide ultra-low power consumption technology and contribute to the promotion of Japanese science and technology, and the strengthening of international competitiveness by promoting integrated electronics business using spintronics technology and power electronics business. In addition to contributing to the advancement of industry-academia collaboration activities, we will contribute to the creation of a prosperous society that is kind to the earth. Thank you in advance for your support and cooperation.

Message from CTO

Tetsuo Endoh
Chief Technology Officer(CTO)

In recent years, development of innovative integrated electronics systems that contribute to intelligent systems as well as energy saving is required in response to energy and labor issues, and society needs to realize Society 5.0, which has been advocated as a form of future society that Japan should aim for. We have developed the innovative core technologies at the Center for Innovative Integrated Electronic Systems (CIES), Tohoku University, in order to improve the performance and increase the density of “Spin-Transfer Torque Magnetic Random Access Memory (STT-MRAM)”, and create IoT devices and AI chips that apply the STT-MRAM for IT/AI fields. In addition, we have been working on research and development of innovative core technologies in power electronics field focusing on compact low-loss power converters using GaN on Si power devices.
On the other hand, in order to connect these R & D activities to the strengthening of Japan’s industrial competitiveness without stopping at the development of science and technology, it is required to create killer applications based on these core technologies and implement them to society at an early stage.
In response to this social demand, we will employ the core technologies that have been researched and developed at the CIES, and integrate them with our various technologies according to each business area with high level. Our mission is to accelerate the social implementation, and established our PSI.
As the first phase business of Power Spin Incorporated. (PSI), we will develop business centering on IoT devices and AI systems that have achieved an increase in computing performance / power consumption ratio over 100 times that of conventional products using spintronics technology.
In particular, we will develop four works as core businesses: 1. Design business of magnetic memory (STT-MRAM) employing spintronics / CMOS hybrid technology, various logic LSIs such as IoT devices and AI chips, and their modules; 2. Prototype business of magnetic memory based on spintronics technologies, and spintronics / CMOS hybrid LSI such as IoT device and AI chip; 3. Sales and licensing business of intellectual properties of various circuit IPs and PDKs related to spintronics / CMOS hybrid technology; 4. Consulting service business in the relevant business domains.
The establishment of PSI is due to the continuous support and cooperation of many people. Your continued support would be appreciated. Moreover,
I sincerely thank you for your continuous support.


We will contribute to the society with dreams and a warm heart through the creation of new value and innovation.


As a start-up from Tohoku University, we will continuously contribute to the social implementation of the technology created by Tohoku Univ., contribute to the advancement of university-industry-academia collaboration activities, and contribute to the creation of a heartful and earth-friendly society.


By promoting integrated electronics business using spintronics technology and power electronics business, we aim to provide ultra-low power consumption technology and contribute to the promotion of Japan’s science and technology and strengthening of international competitiveness.
