Rapid Programming Algorithm
A 50 s PGM 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 PGM 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
PP
is
pulse. If the word fails to verify after 10 pulses have been
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.
PP
is then lowered to 5.0V and V
CC
to 5.0V. All
