    If you are trying to use an SD card as memory for a microcontroller, then you can use SPI to interface the card to the chip.

    Your code will shuffle out the data.

    If you want to use is as a "disk drive" with your PC, you need hardware and a driver to make the card accessible to the operating system.

    If you are using a PIC18, PIC24 or dsPIC30/33 microcontroller, the Microchip Disk Drive library implements an entire FAT32 filesystem read/write driver and allows you to use an SD card with it. As the name implies, it was written by Microchip; AFAIK, it is royalty free.

    Do be careful with SD cards though. In some circumstances to sell devices utilising SD cards you may need a license from the SD card consortium. I'm not sure if it only applies for the specification document, though. Or maybe it's only for manufacturing SD cards.
