A memory system, memory interface device and method for a non-power-of-two burst length are provided. The memory system includes a plurality of memory devices with non-power-of-two burst length logic and a memory interface device including non-power-of-two burst length generation logic. The non-power-of-two burst length generation logic extends a burst length from a power-of-two value to insert an error-detecting code in a burst on data lines between the memory interface device and the plurality of memory devices.
