3D NAND(three-dimensional NAND type)has rapidly become the standard technology for enterprise flash memories,and is also gaining widespread use in other applications.Continued manufacturing process improvements are es...
In traditional 3D NAND design,peripheral circuit accounts for 20-30%of the chip realestate,which reduces the memory density of flash memory.As 3D NAND technology stacks to 128 layers or higher,peripheral circuits may ...
