A Small Ripple and High-Efficiency Wordline Voltage Generator for 3-D nand Flash Memories
IEEE Transactions on Very Large Scale Integration (VLSI) Systems（2021）
Abstract
This article presents a small ripple and high-efficiency wordline (WL) voltage generator to supply voltage to the selected/unselected WLs for program and read operation in 3-D NAND Flash memories. With the proposed scheme of dynamic pump clock voltage and frequency scaling, the output ripple voltage can be minimized to reduce the variation of threshold voltage of the memory cells and the efficienc...
