Nor Flash

Dear

I'm using NOR flash S29JL064H.

Does RY/BY# work if trying to program the same address twice without erase?

In normal case RY/BY# will change from low to high when the program completed

but I'm not sure about the case of programming twice...

Regards,

Hi,

Yes, RY/BY# pin will work, when you try to program the same address without erase. Are you facing any issues with RY/BY# pin behavior after a re-program operation.

Please note, it is not recommended to re-program a memory location without erase. Could you please clarify, why you want to perform re-program operation without erase?

Thanks and Regards,

Sudheesh

Dear Sudheeshk_26

Thank you for your reply. The answer is the same as my expectation.

We don't want to write the flash twice. I wanted to confirm the behavior if the flash is written by some mistake.

Regards
