Note 2
Parameter
Time required for one erasure execution
The total time for repetition of the unit erase time (255 times max.) until the data is erased completely.
Note that the prewrite time and the erase verify time (writeback time) before data erasure are not
included.
Number of rewrites per block
If a block erasure is executed after word units of data are written 512 times to a block (2 KB), it is
considered as one rewrite. Overwriting the same address without erasing the data in it is prohibited.
