Title: A Smart Hybrid Solid-State-Drive Storage System based on Nonvolatile Storage-Class-Memories – Device, Circuit Design and Architecture


Recently, there are many kinds of non-volatile memories like NAND flash, MRAM, PCM and ReRAM. Since there is no perfect non-volatile memories, a co-design of device, circuits and systems is essential in order to achieve high performance and reliability with low cost and power consumption. To reach this goal, this paper proposes a hybrid solid-state drive based storage system with optimum circuits to manage each non-volatile memory characteristics.


He received the B.E, M.E.and Ph.D. degrees in electrical engineering from Hiroshima University, Higashi-Hiroshima, Japan, in2002, 2004, and 2007, respectively. He is currently an Associate Professor at Shinshu University, Nagano, Japan. He was involved with theInterdisciplinary Research Project on Integration ofSemiconductors and Biotechnology from 2007 to2009. He was an Assistant Professor of HiSIMResearch Center, Hiroshima University from 2009to 2010. From 2010 to 2014, he worked for non-volatile memory devices, circuits and systems as a Post-Doctoral Researcher and Assistant Professor at Takeuchi Laboratory inThe University ofTokyo and Chuo University, Tokyo, Japan.

His current research interests include low-power design, computer system, biomedical circuits, high-voltage circuit design and package.
