High-speed Read and High-capacity 3D NOR Flash

"2D NOR is facing the dilemma of being unable to increase memory density through further device size reduction (with a limit of 512 Mb). By using innovative 3D vertical stacking processes, 3D NOR has been developed, reaching a density of 4Gb, with electrical performance matching that of 2D NOR. Future increases in density can be achieved simply by adding more memory layers. Currently, Macronix is the only company worldwide developing 3D NOR products. The demand for high-density NOR, in applications such as 5G, automotive electronics, and artificial intelligence robots, continues to rise."
