JFFS' (Journaling Flash File System) was a file system for use in the Linux operating system for flash memory devices. It was superceded by JFFS2.
JFFS treats the memory device as a circular log, writing to sections of it in order until space runs out and garbage-collection needs to be done, to deal with the characteristic of flash memory that erasing a section of memory for rewriting is a slow process which can only be done a limited number of times before the device wears out.
