| Post subject: | Why tlc nand flash memory have so big page size |
I recently i have access to a vnr, I am thinking of starting in data recovery, and called my attention the page size that appears in the tlc memory configuration 27648 bytes but the real page size is 9216. The person who allowed me to use the vnr did not know how to answer. I started to read a lot of papers but i dont find a answer, i dont read and write very well in english. If any one can answer my question i am very glad, or what paper to read |

In case of WL protocol there are 3 pages (partial pages? virtual pages? physical pages? don't know. There's a mess in flash industry with lack of standards) sitting on the same ROW address. In order to read all 3 of them one must issue 3 different PAGE READ commands with same ROW address to read it out. So, technically, those chips have "physical" page size of 3x9216B = 27648B. Hope this helps. |
