Re: RASTER: M2716A-2F1 datasheet

So, in continuing this discussion on techtoolslist - I found that I was
only about to program a couple more 2716a's and the rest failed. Then I
realized that sometimes I had to program them two or three times until
they finally verified correctly. Has anyone else run into this issue?
