    • An integrated circuit is provided comprising at least one array of memory cells having a plurality of rows of memory cells and a plurality of columns of bit cells. Each column of the memory cells is coupled to one of a plurality of bit lines. Each row of the memory cells is coupled to one of a plurality of word lines, to control coupling of that row of memory cells to the plurality of bit lines in dependence on a respective word line signal. Word line driver circuitry is configured to group together the word lines of at least three rows of memory cells, such that the word lines of the at least three rows of memory cells share a common word line signal. Thus in a write operation a written data value written into the array of memory cells is written to at least three memory cells having a shared bit line. Read circuitry is coupled to the plurality of bit lines, configured such that in a read operation, in which the at least three memory cells are all coupled to the shared bit line by means of the common word line signal, a read data value is determined in dependence on a voltage of the shared bit line, dependent on data values stored in the at least three memory cells. If, at a time of the read operation, one of the at least three memory cells holds a complement value of the written data value, the voltage of the shared bit line nonetheless has a value such that the read data value is determined with the same value as the written data value.

    • A device and a method for measuring and quantifying waviness of sheet materials such as paper. The device in accordance with one embodiment comprises a base having a planar, smooth, and level upper surface for supporting a stack of sheets thereon, a plate-shaped weight for placing atop the stack of sheets, and a measuring device for measuring a vertical distance between a datum surface defined by the weight and a datum surface defined by the base. The measured distance is an indication of the height of the stack. In a preferred embodiment, the device also includes a programmed processor operable to calculate a “Wavy Ratio” based on the measured actual height H of the stack and a calculated “ideal” height of the stack, as Wavy Ratio=H/(n·t), where n is the number of sheets and t is the average caliper of the sheets.
