    Abstract: A method and apparatus for memory power and/or area reduction. An array of memory cells may be scanned to detect faulty memory cells, if any, in the array. A supply voltage Vmem applied to the array of memory cells may be controlled based on a result of the scan, and based on a sensitivity coefficient of one, or more, of the array of memory cells. The sensitivity coefficient may indicate an impact that the one, or more, of the array of memory cells being faulty may have on the performance of a device that reads and writes data to the memory array. Additionally or alternatively, the physical dimensions of the memory cells may be determined based on the sensitivity coefficient(s) and/or based on a number of faulty memory cells that can be tolerated in the array of memory cells.

    Abstract: A coupling device for use in a hybrid fiber coaxial (HFC) network may be configured to disable an upstream path through it when there is only noise incident on the upstream path, and enable the upstream path through it when a desired transmission from a cable modem downstream of the coupling device is incident on the upstream path. The coupling device may be a trunk amplifier, a distribution amplifier, a splitter, or the like. The coupling device may comprise a single upstream interface coupled to a plurality of downstream interfaces. The enabling and/or disabling may be in response to a signal strength indicated by the SSI being below a threshold and/or in response to one or more control messages indicating whether any downstream cable modem is, or will be, transmitting.
