Apparatus and Method for Manufacturing a Multiple-Chip Memory Device

An apparatus for manufacturing a multiple-chip memory device, comprising:

• means for making a volatile memory element on a semiconductor substrate;
• means for examining the volatile memory element for one or more initial errors;
• means for correcting the one or more initial errors on the semiconductor substrate;
• means for incorporating the volatile memory element into the multiple-chip memory device;
• means for incorporating a non-volatile memory element into the multiple-chip memory device;
• means for examining the volatile memory element for one or more secondary errors, after the means for incorporating incorporates the volatile memory element and the non-volatile memory element into the multiple-chip memory device;
• and
• means for storing repair information in a non-volatile memory element, the repair information identifying the one or more secondary errors.
