Future development trends of 3D NAND technology

With the continuous development of 3D NAND technology, it is projected that by 2030, the memory industry will be able to achieve 3D NAND flash memory chips with more than 1,000 layers, with a storage capacity of approximately 100 Gbit/mm². To achieve this goal, the industry is exploring a variety of new technologies, including air-gap integration and charge trap layer separation.
