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.

NOR Flash FAQs - KBA222273

[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,

Apurva

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.
