Rapid Programming Algorithm
A 50 s CE pulse width is used to program. The address is
set to the first location. V
raised to 13.0V. Each address is first programmed with one
50 s CE pulse without verification. Then a verification /
reprogramming loop is executed for each address. In the
event a word fails to pass verification, up to 10 successive
50 s pulses are applied with a verification after each
CC
is raised to 6.5V and V

applied, the part is considered failed. After the word verifies
properly, the next address is selected until all have been
checked. V
words are read again and compared with the original data
to determine if the device passes or fails.
