Storage unit on DE2

Hei there.

Using the DE2 Bord, i want to record my voice, and store it in a memory unit, and after that to play my voice when i press a button.

Can i make a storage unit on the FPGA? And if so, what do you recomand? Or is it better to use the memory card unit, or the storage unit allready on the bord?

The ideea is that i want to record more that one time, and to use whatever registration i want, when i want, and if possible, to creat the storage unit myself.

Thank you!
