The ability to erase before packaging allows for complete testing of the memory chip prior to shipment, which is a distinct advantage over once-programmable ROMs. Erasure of information in packaged devices by placing them in a commercially available X-ray generator allows for correction of programming errors as well as unpredictable future pattern modifications.",
