program and erase endurance is counted as one time.
The program and erase endurance shows an erase endurance for every block.
If the program and erase endurance is “n” times (n = 100), “n” times erase can be performed for every block.
For example, if performing 1-byte write to the distinct addresses on Block A of 2Kbyte block 2048 times and then erasing that block,
However, do not perform multiple programs to the same address for one time erase. (disable overwriting).
