flash max number of writing ?

[Lennart]

Hello !

I have read in DevZone, but still not sure regarding nRF52832 .

For nRF52832 and page size 4k, and regarding only writing zero-bits.

Can I in same page perform total 6144 number of 32-bits writings (6 times each 32-bit address) without erase that 4k page?

Edit: "corrected to 6 times".

Best regards Lennart Vedin for tss.se

This is a general feature of Flash memory - not specific to Nordic.

It is the erasing which causes the wear - not the writing of zeros.

See the pencil-and-paper analogy here: https://www.violinsystems.com/all-flash-storage/how-flash-storage-works/

The way so-called wear-levelling schemes work is to write to different locations in the page, and only do an erase when the whole page has been used up.
