  • Patent number: 8468401
    Abstract: A method for manufacturing a multiple-chip memory device includes making a volatile memory element on a semiconductor substrate, examining the volatile memory element for one or more initial errors, correcting the one or more initial errors on the semiconductor substrate, incorporating the volatile memory element into the multiple-chip memory device, and incorporating a non-volatile memory element into the multiple-chip memory device. The volatile memory element is examined for one or more secondary errors, after incorporating the volatile memory element and the non-volatile memory element into the multiple-chip memory device. Repair information is stored in a non-volatile memory element, the repair information identifying the one or more secondary errors.
    Type: Grant

  • Publication number: 20080237587
    Abstract: A device or method for effectively stressing an interconnect in a test current path of a semiconductor device, which test current path is other than a current path used during normal operation of the semiconductor device. An operational voltage is adjusted to a test voltage, the test current path is opened and the test voltage is supplied to the test current path.
