    摘要: A memory system supports high-performance and low-power modes. The memory system includes a memory core and a core interface. The memory core employs core supply voltages that remain the same in both modes. Supply voltages and signaling rates for the core interface may be scaled down to save power. Level shifters between the memory core and core interface level shift signals as needed to accommodate the signaling voltages used by the core interface in the different modes.

    摘要: The disclosed embodiments provide a dynamic memory device, comprising a set of dynamic memory cells and a set of replacement dynamic memory cells. The set of replacement dynamic memory cells includes data cells which contain replacement data bits for predetermined faulty cells in the set of dynamic memory cells, and address cells which contain address bits identifying the faulty cells, wherein each data cell is associated with a group of address cells that identify an associated faulty cell in the set of dynamic memory cells. The dynamic memory device also includes a remapping circuit, which remaps a faulty cell in the set of dynamic memory cells to an associated replacement cell in the set of replacement cells.

    摘要: 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.
