We now have a documented case where the DATA IO programmed a 27128-2 
and verified it.  Yet the AMS will read some of the data as 00's.  Even more
amazing is that the IMI does not verify the part and also reads 00's where
there should be a valid opcode of 23.  When we ask the DATA IO to read the
failing address it reads 23 which explains why it verifies the part.
