Outline

We develop a 3D magnetic memory consisting of an artificial ferromagnetic material composed of a recording layer/magnetic domain wall layer. The proposed three-dimensional magnetic memory will have the same high speed as volatile memory DRAM and the same high density and low cost as non-volatile memory 3D-NAND due to the features of three-dimensional structure, non-volatility of magnetic material, high-speed spin dynamics, and multi-level memory shift register.

Outline

As the information carrier for developing an advanced information society, we focus on terahertz waves in the untapped electromagnetic spectrum between radio waves and light. We create novel electronic devices to control the time domain and the space distribution of terahertz waves through the fusion of quantum effects and photonics into electronics.

Outline

Utilizing the acceleration vibration as an information carrier, ultra-fine vibration measurement devices are developed and information hidden in the ultra-fine vibration is decoded in this project. Specifically, the very first wide-range, wide-band and three-axis multimodality information carrier system in the world is constructed to analyze of neural information from the vibration of fine muscle sound and motor information from the various movement simultaneously. Furthermore, early diagnosis of Parkinson’s disease by developing a multimodal decoding algorithm based on the relationship between information obtained from the neural system and the motor system is a target.
