Methods and apparatus are provided for a system for aligning data. The apparatus comprises a demultiplexing component adapted to bifurcate a double data rate (DDR) data stream into a first single data rate (SDR) data stream and a second SDR data stream, a bit detection component coupled to the demultiplexing component and adapted to compare bit values between the first and second SDR data streams and generate a first signal in response to detection of a predetermined arrangement of bits, a delay component adapted to receive the DDR data stream and perform a delay operation on the DDR data stream to create a delayed data stream, and a data alignment component coupled to the demultiplexing component, the delay component, and to the bit detection component, the data alignment component being adapted to place the delayed data stream in alignment in response to the first signal.
