Xbox One comes with an additional 8GB of NAND flash memory, according to details revealed in a recent Xbox One teardown by iFixit. We have the snapshot of Xbox One Architecture showing where this 8GB of NAND flash memory is located.
The manufacturing model is SK Hynix H26M42003GMR 8 GB eMMC NAND Flash, a quick search on internet states that SK Hynix is a South Korean firm which deals in semiconductor technologies delivering RAM and flash memory.
Neither Microsoft nor iFixit teardown reveal details regarding 8 GB of NAND Flash Memory and for what it is used in Xbox One. The specification details about this chip (again discovered via quick Google Search) reveals that SK Hynix H26M42003GMR features density of 32GB (i.e the amount of data that can be stored in a given area).
We have contacted Microsoft (especially Albert Penello) for some official words on what’s the purpose of 8 GB of NAND Flash Memory on Xbox One. Stay tuned to Gamepur as we will update this post as we get to hear something from them.
