interesting question. Perhaps some sort of journaling scheme so that you never (well very rarely) rewrite the same bytes in the map. Perhaps they have a little amount of other memory that doesn't mind beeing rewritten so often. Or perhaps each memory block has its sector number & version stored inside and a map is recreated from this information after poweron ins some aux RAM. Bye Richard
