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 16 times for different
addresses in 4-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. The result obtained from the reliability test.
