When the number of times is 100, it can be erase 100 times for each blocks. However, for ine erase it can not be writed in the same adress two or more times(forbiddance of overwriting). Note 2: It is the minimum number of times which guarantees all the characteristics after program/erase (guarantee is the range from "1" to "minimum" value.
