18. Rapid Programming Algorithm

A 100 µs PGM pulse width is used to program. The address is set to the first location. V

raised to 6.5V and V

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 100 µs pulses are

applied with a verification 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

read again and compared with the original data to determine if the device passes or fails.
