Note 1. Definition of reprogram/erase cycle:
The reprogram/erase cycle is the number of erasing for each block. When the reprogram/erase cycle is n times (n = 1000),
erasing can be performed n times for each block. For instance, when 256-byte programming is performed 32 times for different
addresses in 8-Kbyte block and then the entire block is erased, the reprogram/erase cycle is counted as one. However,
programming the same address for several times as one erasing is not enabled (overwriting is prohibited).
Note 2. This is the minimum number of times to guarantee all the characteristics after reprogramming (guaranteed range is from 1 to the
value of the minimum value).
Note 3. This shows the characteristics when reprogramming is performed within the specified range, including the minimum value.
