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!
