Embedded system design is a complex game. In pursuit of a NAND flash-based storage system that’s both reliable and robust, one must consider many different factors. Chief among them is the flash controller.
When it comes to SSDs, USB flash drives, eMMC modules, SD cards, and other forms of managed NAND devices, the controller plays a pivotal role, as it’s responsible for regulating system behavior and reliability. Designers are further tasked with optimizing flash controllers for peak performance and cost efficiency, particulars that vary depending on specific industry and use-case demands.
