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 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. 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.
