The Express algorithm has been developed to improve on the programming throughput times in a production environment. Up to ten 100-microsecond pulses are applied until the byte is verified. A flowchart of the Express algorithm is shown in Figure l-3. Programming takes place when: a) vcc is brought to the proper voltage, b) tjENPP is brought to the proper VH level, and c) line is low.
