の書込み回数の上限値を教えて頂けないでしょうか?
Hello Daibosatu,
(Your Google translated question: Could you please tell me the upper limit for the number of writes?)
The datasheet does not explicitly state the upper limit to the number of writes to the flash memory, but it does state that the minimum number of erase cycles per sector is 100,000 cycles. Since one cannot write again to the same memory address before first erasing that memory address, this means that the guaranteed minimum number of writes to a sector of flash is also 100,000 cycles.
It may be able to handle substantially more than 100,000 cycles, but there is no way to know how many more cycles because it is dependent upon multiple variables including environmental conditions, the specifics of how one’s circuit operates, variations in die characteristics, plus other possible factors. Therefore, they guarantee that it will be able to write at least 100,000 cycles, but they will not specify the maximum number of cycles, as that is not predictable.
From page one of the datasheet:
• JESD47H-compliant
– Minimum 100,000 ERASE cycles per sector
– Data retention: 20 years (TYP)

毎度お世話になっております。
英文で回答がございました。
書き込み回数の制限は、消去回数の制限と同じで10万回とのことです。
ご回答としてはこれでよろしいでしょうか。
もし追加でご質問がございましたらお知らせください。
よろしくお願いいたします。
ご回答ありがとうございます。
大変、助かりました。
ご協力いただきありがとうございます。
