Please excuse me for the Delay.

Flex-OneNAND device's erasesize itself is double considered to OneNAND.
Like , In SLC region of Flex-OneNAND size is 256K and 
in MLC region it is 512K. In case of OneNAND erasesize is 128K and 
it is just SLC.

That's the reason size doubles for the Env in SLC and 
for MLC increased by one more fold.

In reply to Alessandro's mail , I have given the same details.
