    (About EEPROM error checking/correction)
    More interesting (or more practical for many purposes) is a check and
    correction scheme which works on single objects instead of the whole
    memory. If you have the requirement to store and load dynamically (and
    frequently) during operation, you need to use a method which
    immediately discovers errors at the moment of transfer into the
    working set of data. Taking into account power losses during write
    often goes hand in hand with other "defensive" strategies. Unluckily
    there isn't too much to find on the net about transaction schemes and
    stable storages (at least not in tech detail, mostly stable storage is
    assumed as a basis to explain sg. different). My implementation is a
    (out-of-fashion?) block oriented, directory-less so-so file system; I
    wonder if there are people in here who have devised/implemented
    different systems. Any hints?
