I haven't experienced it with flash, but with good old EPROM. However, 
the theory is the same: from time to time an elementary charge 
escapes  from the floating gate. So after some time (usually 
>10years) bits get lost.

CRC will most likely detect this, at least if the check routine itself 
remains unchanged ;-)
