- I have managed to get a 2764 to retain data using a 1ms pulse time, even though the
- data states 40ms minimum, 50 ms typical. I found this while testing and setting up
- a DIY Eprom programmer.
-
- How long the data retains for, I dont know, but I wouldnt have thought it would work
- at that sort of speed!
