    Abstract: A memory module with multiple memory devices includes a buffer system that manages communication between a memory controller and the memory devices. Each memory device supports an access mode and a low-power mode, the latter used to save power for devices that are not immediately needed. The module provides granular power management using a chip-select decoder that decodes chip-select signals from the memory controller into power-state signals that determine which of the memory devices are in which of the modes. Devices can thus be brought out of the low-power mode in relatively small numbers, as needed, to limit power consumption.

    Abstract: A pixel array within an integrated-circuit image sensor is exposed to light representative of a scene during a first frame interval and then oversampled a first number of times within the first frame interval to generate a corresponding first number of frames of image data from which a first output image may be constructed. One or more of the first number of frames of image data are evaluated to determine whether a range of luminances in the scene warrants adjustment of an oversampling factor from the first number to a second number, if so, the oversampling factor is adjusted such that the pixel array is oversampled the second number of times within a second frame interval to generate a corresponding second number of frames of image data from which a second output image may be constructed.
