NOR flash, a type of non-volatile memory technologies, embraces its new age of IoT due to its execute-in-place (XIP) feature. Generally, there are two representative file systems designed for NOR flash: Journaling Flash File System 2 (JFFS2) and Spi Flash File System (SPIFFS). They suffer from eithe...
