Rapid programming algorithm
A 100 μ s CE pulse width is used to program. The address is set to t he first location. V CC is raised to 6.5V and V PP is
raised to 13.0V. Each address is first programmed with one 100 μ s 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 ten
successive 100 μ s pulses are applied with a verification after each pulse. If the byte fails to verify after ten 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 PP is then lowered to 5.0V 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.
