Summary:A memory controller that can determine a swizzling pattern between the memory controller and memory devices. The memory controller generates a swizzling map based on the determined swizzling pattern. The memory controller may internally swizzle data using the swizzling map before writing the data to memory so that the data appears in the correct order at the pins of the memory chip(s). On reads, the controller can internally de-swizzle the data before performing the error correction operations using the swizzling map.
