Does FLASH_Erase always erase entire sector without restoring any part of it?

That is, if I only need to erase 12 bytes, will the entire 1K sector be erased without the other 1012 bytes being retained/restored?  The KSDK v2.0 API reference manual is unclear about this.  I need to know if I need to manually backup the data to be retained and restore it after the erasure.
