They are laminated screws. They have a protective coating on them to resist corrosion and to 'slide' through the cementious material of the board. The design of the head also does a better job at 'grabbing' the board and pulling it tight to the framing members.
As mentioned already, there is a manufacturer that makes 'Rock On' - "Cement Board Screws". Most Drywall suppliers carry them. I also know that HD carries them.
