  • Publication number: 20150279487
    Abstract: An integrated circuit includes a set of non-volatile bits that may be programmed during multiprobe testing of the integrated circuit (IC). A defective portion of the IC is identified by testing the IC during multiprobe testing prior to packaging the IC. The IC is scrapped if the defective portion of IC does not meet repair criteria. A defect category is selected that is indicative of the defective portion, wherein the defect category is selected from a set of defect categories. The defective portion is replaced with a standby repair portion by modifying circuitry on the IC. The selected defect category is recorded in a plurality of non-volatile bits on the IC. The non-volatile bits may be read after extended testing or after end-user deployment in order to track failure rate of repaired ICs based on the defect category.

  • Patent number: 9147193
    Abstract: Embodiments of the invention provide methods for maximizing the bandwidth utilization in the uplink of a communication system supporting time division multiplexing between unicast and multicast/broadcast communication modes during transmission time intervals in the downlink of a communication system. This is accomplished by multiplexing at least unicast control signaling for UL scheduling assignments in TTIs supporting the multicast/broadcast communication mode. Moreover, multiplexing of unicast control signaling can also be accomplished by splitting a symbol of the multicast/broadcast TTI into two shorter symbols with the first of these two shorter symbols carrying at least unicast control signaling and the second of these shorter symbols carrying multicast/broadcast signaling.
