The mark consists of a pair of stacked rectangles, where the top rectangle is light gray and the bottom rectangle is dark gray. A gray rectangular frame is disposed between the spaced rectangles. A gray vertical line extends through the rectangles and frame, where a gray arrowhead is disposed on the top end of the line and an orange circle is disposed on the bottom end of the line. The phrase "HMPS Memo module" is below the orange circle, with the word "Memo" being in orange and the remaining terms in gray. The color white merely serves as background and is not claimed as a feature of the mark.
