A variety of NAND flash architectures, the constant migration to newer, more advanced process technologies, and the continual introduction of new features have converged to make the design of NAND flash memory subsystems more challenging than ever.
The current situation in the NAND flash market presents designers with three options. They can build their own discrete solutions using flash controllers and separate NAND devices. They can use embedded NAND controllers (within chipsets/processors) along with separate NAND devices. Or they can opt to buy managed NAND solutions that offer the entire NAND memory subsystem in a pre-packaged solution.
