Is it possible to connect any FPGA board to a dimm slot directly?

Hi, We are looking for a FPGA solution which can be used for replacing the DRAM and connect a FPGA board to a dimm slot directly. The DRAM should be on the FPGA board. What we want to do i...

SDRAM interfaces are fast, and the interface timing is fixed for a given memory. Some interfaces allow insertion of wait states to slow things down, but SDRAM is not one of those interfaces. It's just not possible to do what you want with a standard memory controller that is not aware of the delay added by the FPGA. You would be better off doing the encryption and decryption in software.
