AP-325 Guide to First Generation Flash Memory Programming

Since 1988, thousands of engineers have written software to direct flash memory reprogramming. With first generation flash memories, one sends a control signal to a device to begin and end programming or erasure. It is a simple process implemented on more than 40 million units, however care must be taken. If algorithms are not properly followed, a device may be rendered inoperable. This document discusses proper software and debug technique, which yields dependable first generation flash memory operation. First generation products include the 28F010 and 28F020. All second and third generation Intel Flash Memories contain automated program and erase routines.
