If you are talking about internal storage (not RAM memory), then yes this is generally flash memory, and you want to be careful about how much you write to it for numerous reasons: also extremely important are the battery impact (writing to flash is expensive) and performance (causing other things that are accessing flash storage to be blocked by what you are doing).
That said, properly designed flash storage won't let you write to the same block over and over. Writes are spread across the flash storage just to avoid that kind of issue.
