Abstract (in Japanese) (See Japanese page) 
(in English) A boost-converter-based adaptive voltage generator for 3D-integrated SSD is proposed. Adaptive frequency and duty cycle controller which optimizes the switching frequency and duty cycle is also proposed. The power consumption reduces by 88%, rise-time reduces by 73% and circuit area of the voltage generator decreases by 85%. The total power consumption during write operation of a NAND Flash memory reduces by 68%.
