  • Abstract
    A low-power program-voltage generator (PVG) using a boost converter with an adaptive-frequency and duty-cycle (AFD) controller is implemented. SSD consists of the HVMOS chip (0.35 x 0.50 mm2), the AFD controller chip (0.67 x 0.28mm2), a 270nH 0.5Omega inductor in an interposer (5 x 5mm2), and a 56 nm 16 Gb NAND Flash memory chip.
