Abstract
In this paper we present an adaptive program-voltage
generator for 3D-integrated so lid state drives (SSDs) based on
a boost converter. The converter c onsists of a spiral inductor,
a high-voltage MOS circuit, a nd an adaptive-frequency and
duty-cycle (AFD) controller . The spiral inductor requires an area
of only 5 5m m in an interposer. The high-voltage MOS circuit
employs a mature NAND flash process. The AFD controller,
implemented in a conventio nal low-voltage MOS process, dynam-
