Completely ;-)

CompactFlash has a parallel interface and this has eight data lines,
three address lines & six control lines.
SD / MMC has a serial inrterface and can be accessed using SPI, only
requiring 3 pins connected to the µC (Mosi, Miso & Sck).

Plus Card Select, which is needed even if there is only one card.
