If you’ve worked on NAND or eMMC management in embedded Linux, you’ve likely come across the term SEMC (Smart External Memory Controller). While often associated with NXP’s i.MX RT and LPC families, the SEMC peripheral is a powerful external memory interface that can be configured to drive various asynchronous/synchronous memory devices—including NOR flash, NAND flash, and even SRAM/PSRAM. semc flash device driver
