I plan on reading and probably writing NAND flash on some embedded devices or USB flash drives.
I did not come across many examples for in circuit reading though I'd give that a try at first if possible. Otherwise I'm going to desolder the NAND flash. For reading I want to use a FT2232H board. I was wondering which of the 48 pins are really required to be connected. Sure there are the obvious ones which are labeled DNU or NC on the spec sheet.
But could I omit connecting some of the ground or voltage pins or some of the IO pins? There are multiple of the latter ones and maybe connecting just one or two of those would be sufficient though maybe reducing the read and write speed.
