Hi Huang,


just out of interest, have you tried this on the MLC NAND without the patch?

I'm aware that MLC says you shouldn't write multiple times, but that is
with a view towards specified data endurance. I would only expect a few
additional bit errors during the test.

Did you try the overwrite test?

I'm curious how MLC NAND does when subjected to multiple writes.


Best regards,

Iwo
