When you have a correctable ECC error on a page you need to rewrite the memory to remove the error. This prevents the correctable error from becoming an uncorrectable error if another bit goes bad. Also if you have a working software memory scrub routine you can be certain multiple errors from the same address are actually distinct. As opposed to multiple reports of the same error.
