  • Patent number: 6882001
    Abstract: An electrically-programmable memory cell programmed by means of injection of channel hot electrons into a charge-storage element capacitively coupled to a memory cell channel for modulating a conductivity thereof depending on a stored amount of charge. A first and a second spaced-apart electrode regions are formed in a semiconductor layer and define a channel region there between; at least one of the first and second electrode regions acts as a programming electrode of the memory cell. A control electrode is capacitively coupled to the charge-storage element. The charge-storage element is placed over the channel to substantially extend from the first to the second electrode regions, and is separated from the channel region by a dielectric layer. The dielectric layer has a reduced thickness in a portion thereof near the at least one programming electrode.

  • Patent number: 6883113
    Abstract: A procedure for temporally isolating an environmentally dependent integrated circuit fault includes the steps of determining a marginally failing and a minimally passing environmental condition corresponding to the fault; identifying a clock cycle Tmax at which the fault was first detected; determining a candidate clock cycle at which the fault may have occurred; and iteratively a) applying test pattern subsets from an initial clock cycle through the candidate clock cycle under the marginally failing environmental condition; b) applying remaining test patterns under the minimally passing environmental condition; and c) adjusting the candidate clock cycle based upon whether the fault occurred during test pattern subset application up through the candidate clock cycle under the marginally failing environmental condition. Candidate clock cycle adjustment in accordance with a binary search technique enables determination of an exact clock cycle at which the fault occurred in a maximum of Log2 (Tmax+1) iterations.
