Rapid programming algorithm
A 100μs CE pulse width is used to program. The address is set to the first location. V CC is raised to 6.5V and OE/V PP is raised
to 13.0V. Each address is first programmed with one 100μs CE pulse 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 100μs pulses are applied with a verification 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. OE/V PP is then lowered to V IL and V CC to 5.0V. All bytes are read again and compared with the original data to
determine if the device passes or fails.
