18. Rapid Programming Algorithm

AT27BV4096
A 50 µs CE pulse width is used to program. The address is set to the first location. V
to 6.5V and V
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
cation after each 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
pared with the original data to determine if the device passes or fails.
