Hello Stefano
My apologies for a late delay. I have been away from my office for the Christmas break.
I looked at the datasheet and I see the following things in the parameter page structure:
* The device supports partial page programming and has 4 partial pages. ie. each page can be treated as 4x512byte sub-page.
* These pages may be programmed individually.
That suggests that this part could be uses in Yaffs1 mode, just with 256 pages of 512 bytes rather than 64 pages of 2k.
However...
* It also says a maximum of 4 programs per page. Since Yaffs1 requires a page be programmed twice: once for programming and once for setting the deletion flag, the above scheme would require 8 programming operations per page.
* It also wants 4 bytes of ECC correction per page. Using Yaffs1 ECC only gives 1 bit per 256 bytes. That is not as good.
