About NOR Flash S29GL256N10TFI010

It is described on page 47 of the above Flash ROM data sheet "Document Number: 002-01522 Rev. * B". According to Figure 9.1 Write Buffer Programming Operation It is written that DQ15-DQ0 should be read again when DQ5 = 1 (see attached figure)

Is there a delay before loading DQ15-DQ0 again? If you need a delay, what is the standard and how many seconds do you need?

The data sheet is below

Hi,

Thank you for contacting Infineon Technologies.

After Writing  program buffer to flash sector address data polling will happen.
Data polling is nothing but, it will check whether the writing/programming operation is complete or not.

DQ bits status will show whether polling is complete or not.

You can refer Page 59 of 92 of data sheet  in order to understand data polling in Parallel Flash.

To answer your query there is no as such delay we need to provide.

Thanks and Regards,

Yuvraj
