Abstract
In an embodiment of the invention, an apparatus for generating a maximum change data pattern, includes: a shift stage configured to shift a generated signal to the right by one bit and to generate a shifted signal; a logic stage configured to perform an XOR function on the signal and the shifted signal, and generate an XOR output signal; a complement stage configured to complement the XOR output signal, and to generate a complement stage output signal; and a selector configured to select the XOR output signal if the generated signal is even and to select the complement stage output signal if the generated signal is odd.
