This has nothing to do with ZFS as a filesystem. It has integrity verification on duplicated raid configurations. If the system memory flips a bit, it will get written to disk like all filesystems. If a bit flips on a disk, however, it can be detected and repaired. Without ECC, your source of truth can corrupt, but this true of any system.
