Is the flash write and erase life total 10000? or separately?

[cemalb]

For flash memory, 10000 write/erase life is specified in the documents. is that means 10000 lifetimes for writing only and 10000 only for erasing? I have to delete the page before every writing. Does it mean I can write 5000 times in such a usage?

It's the erasing that causes the wear.

After erasing, the only 'write' that's possible is to change a '1' (erased) bit to a '0'.
