The principle behind this patch is to modify the perception capability of the Reader unit towards low voltage signals, rather than relying on an external level-shifting chip. About six months ago, I attempted to address reading VCCQ 1.8-1.2 Low VCCQ NAND Flash by creating additional adapters. However, on certain chips, this approach significantly reduced the reading quality. I cannot tolerate such results, so despite producing dozens of these adapters in small batches, they are all sitting unused in a corner now. The current solution I have developed is the best one I have tried so far. With the modified Reader, certain chips like 45 3C 98 B3 achieve a more stable dump quality compared to the original Reader.

This is very cool mod, but I see that it is required to desolder the FPGA and solder again. If it's work that good news I quick check and this old Altera Cyclone also use 1,5V and 2,5V for VCCIO, saddy no 1.2V - this voltage is support form Cyclone III But if only 1.8V do the work, I am interested in this modification.
