18. Rapid Programming Algorithm
A 100
s CE pulse width is used to program. The address is set to the first location. V
is raised
µ
CC
to 6.5V and V
is raised to 13.0V. Each address is first programmed with one 100
s CE pulse
µ
PP
without verification. Then a verification/reprogramming loop is executed for each address. In the
event a byte fails to pass verification, up to 10 successive 100
s pulses are applied with a veri-
µ
fication after each pulse. If the byte fails to verify after 10 pulses have been applied, the part is
considered failed. After the byte verifies properly, the next address is selected until all have been
checked. V
is then lowered to 5.0V and V
to 5.0V. All bytes are read again and compared
PP
CC
with the original data to determine if the device passes or fails.
