DDR3 and DDR2 at the same time, NIOS II

Honored Contributor II

I'm designing a board using a Cyclone V FPGA, I using the reference design of the Cyclone V E Development Kit Board ( 5CEFA7F31 ), this chip have two hard memory controllers, the Development Kit Board use one controller for DDR3 memory (2x256MB) and the other memory controller have LPDDR2 512MB. I have some doubts, now i'm in the schematic design (memorypart) Can I use the two memory controllers at the same time? The two controllers must have the same kind of memory ? The 5CEFA7F31 doesn't have hard processor, so i will use NIOS II, what is tha maximum memory that it can use? thanks in advance
