*1. Determination of the number of times for programming/erasure operations.
*2. This is the number of times for which all electrical characteristics are guaranteed.
When the number of times for programming/erasure operations is n (n = 100), data can be erased
For example, if programming of 4 bytes is done 1024 times, each at a different address in a 4-
However, programming of any location in a block multiple times is not possible (overwriting is
programming operations by shifting the writing addresses in sequence and so on until the
remaining blank area is as small as possible and only then erasing the entire block once. For
example, if sets of 16 bytes are being programmed, erasing the block once after programming the
maximum number of sets (256) minimizes the effective number of programming operations.
We recommend keeping information on the number of times erasure is performed for each block,
and setting up the limit on the number of times.
