Hello,
The FL-S (Mirrorbit) series is described in the following Community as having a built-in ECC function.
Use Cases that Disable Automatic ECC on the Mirrorbit 65nm Flash Family – KBA222872
The FL-L series is a floating gate. Does it have a built-in ECC function?
The following Community 38 states that FL-L also has ECC functionality.
[38. In what cases can ECC be invalid in FL-S/FL-L?]
This question has the background of wanting to confirm whether it is okay to execute a 1-byte Page Program at the following address after executing a 1-byte Page Program with FL-L (64Mbit).
Best regards,
Takahashi

Hi Takahashi san,
I would like to inform you that FL-L does not have ECC.
We will raise an internal request to get the KBA fixed.
Thank you and Regards,

Hi Apurva-san,
Thank you for your reply.
Just in case, let me check.
I think it is possible to perform a Page Program (PP) every 1 byte.
In that case, you can write to the following address, right?
[Example]
1st time : PP (0x02h) - 3Byte address (0x000000) - 1byte data (any)
2nd time : PP (0x02h) - 3Byte address (0x000001) - 1byte data (any)
3rd time : PP (0x02h) - 3Byte address (0x000002) - 1byte data (any)
:
:
I think the write performance will be worse, but I would like to check if this method can also be used.
Do I have any other concerns?
Best regards,
Takahashi

Hi Takahashi san,
Yes, the above mentioned write operations can be performed, and also yes for write performance being poor.
