... NMC27C64 is programmed with the Fast Programming Algorithm shown in Figure 1. Each address is programmed with a series of 100 s pulses until it verfies good maximum of 25 pulses. Most memory cells will program with a single 100 s pulse. The NMC27C64 must not be programmed with a DC signal applied to the PGM input. ...
