Gwan-Hyeob Koh
Biography
Daniel Worledge, Guohan Hu, and Gwan-Hyeob Koh developed the world’s first embedded Spin-Transfer Torque Magnetoresistive Random Access Memory (STT-MRAM) technology. Their work resulted in Samsung offering eMRAM at the 28 nm node and below for embedded non-volatile memory (eNVM) applications. Non-volatile memory is used to store information when the power is off and is already improving society by reducing energy usage in products sold today. Going forward, STT MRAM will be used to create smarter and more power-efficient products for a wide range of consumer, industrial, and automotive applications.
Koh engaged in memory device development at Samsung Electronics for 25 years and is currently serving as a Professor of Industry Partnerships, Sungkyunkwan University, Republic of Korea and was the co-recipient of the 2025 IEEE Cledo Brunetti Award for "contributions to the development and commercialization of embedded Spin-Transfer-Torque Magnetoresistive Random-Access Memory (STT-MRAM) technology."
