17.3.2 Write/Verify and Electrical Characteristics
Write/Verify: Write/verify can be accomplished by an efficient high-speed, high-reliability
programming method. This method can write data quickly and accurately without placing voltage
stress on the device. The basic flowchart for this high-speed, high-reliability programming method
is shown in figure 17.4.
