*1. Determination of the number of times for programming/erasure operations.
Number of times programming/erasure is performed in each block.
When the number of times for programming/erasure operations is n (n = 100), data can be erased
n times in each block.
For example, if programming of 4 bytes is done 1024 times, each at a different address in a 4-
kbyte per block, and the block is then erased, this counts as programming/erasure one time.
However, programming of any location in a block multiple times is not possible (overwriting is
prohibited).
*2. This is the number of times for which all electrical characteristics are guaranteed.
