Abstract

Ultra-violet erasable PROMS have the capability of being erased by ultra-violet light. Unfortunately, there is no method of determining their erasure by inspection. Also, the variety of W intensities produced by ditferent erasers precludes any kind of universal erasure time for each EPROM. Even multiple EPROMs within the same eraser receive ditrerent amounts of light, occasionally resulting in some EPROMs being erased while others are not.
