Patent WO-2021207965-A1 (WO)
Title: 3d nand flash and operation method thereof
Inventor: LIU HONGTAO
IPC: G11C16/10
Filed: 2020-04-15
Abstract: A programming method of an increment step pulse program (ISPP) for a three-dimension (3D) NAND flash includes programming a select wordline of an unselect bit line of the 3D NAND flash; performing a first verification process with at least a verification voltage on the select wordline; determining whether a first verification voltage of the first verification process for the select wordline is higher than a default voltage or not; and removing a pre-pulse phase of the ISPP when the first verification voltage is higher than the default voltage; wherein the first verification voltage is a following verification voltage of the first verification process.
