Methods and apparatus for storing and retrieving data in parallel but in different orders, using three or more memory devices. In one implementation, data for pixels is stored according to a checkered pattern, sequentially among memory devices, forming a checkerboard buffer. In one implementation, a checkerboard buffer includes: a data source, providing data in a first order; a data destination, receiving data in a second order; at least three memory devices each having memory locations, where data is stored in parallel to and retrieved in parallel from the memory devices; a first data switch connected to the data source and each of the memory devices, the first data switch controls which data is stored to which memory device; and a second data switch connected to the data destination and each of the memory devices, the second data switch controls providing data to the data destination according to the second order.
