There is no problem with only writing a partial page on these devices, i.e. you can write anything from one byte up to the full page size (32 bytes for 24LC64 IIRC) in a single write.  Things only get a little more complex when you want to write a block of data and it overlaps the eeproms page size, but this really isn't very difficult to handle.
