A x-y RAM array with a reconfigurable bit width is provided. The array contains a RAM cell columns organized into a number of column groups where the number of groups determines the bit width of the memory. The number of columns in each group are configurable thereby configuring the number of groups and thus the bit width of the memory. Multiplexor logic selects a column from each group to be accessed and passgate logic determines how the multiplexor logic is combined and thus determined the column group configuration. Decode logic provides the appropriate select signals to the multiplexor logic for selecting from the configured number of columns in each group.
