SD card design

Hello,

I am designing a system which consists of RAM and storage device (SD card, for example). The RAM will temporarily store data coming in and write that data to the storage device. I managed to get Quartus generated RAM, but I am lost with storage device. Should I use ROM or is there any alternative way?

    What would you use ROM for?

    The easiest way to interface with an SD-card is using SPI. To that end, you'll need to write an SPI block and some way of controlling that. While can probably do this with a state-machine, having some sort of CPU would be easier.

    Hope this helps,
