This is also not really correct.  You can write all you want to, 

although only writing bits from one to zero will succeed.  The 

write/erase cycle endurance tells you how many times (minimum) you can 

erase a bit that has been written to zero or, perhaps, how many times 

you can erase a sector in which any of the bits have been written to 

zero.  It's the erase that counts.  Since erases are sector based, each 

sector wears out independently of the others.  In practice, you can 

think of the endurance limit as the number of times you can reprogram 

the chip, which is probably what you meant.



Graham.
