I believe that the devices are memory dies but cannot be sure as my microscope if not good enough to get the full detail. To my amateur eye it looks like it could be FLASH memory- almost certainly it is memory of some sort. These are manufacturing pulled wafers- 100% perfect wafers would cost in excess of $500(US Dollars) and in any case would not be for sale on eBay as the manufacturer always destroys any surplus wafers. There will be some imperfections and micro scratches and this is just part and parcel of buying used wafers- you gotta live with it! The gallery photo shows how this wafer looks under halogen lighting- stunning eh? The second and third photos are of the wafer under a simple neon tube desk lamp. Note the lovely blue oxide finish on the reverse. The other photos are of the wafer die pattern under my cheapo USB microscope. Wafer will be well packed with plenty of bubble and space to breathe- posting is by Registered Airmail with a tracking number that can be used to trace the item. gsrx_vers_476(GS 6.4.4(476)
