4.6.2.2. DDR4/DDR-T DIMM Memory Interface
The DIMM Memory interface uses a standard 288-pin DIMM connector that is mapped to the FPGA’s 3I, 3J, 3K and 3L I/O blocks. The connector supports plugins for the following memory interfaces:
- DDR4 x72 (included in the kit)
- DDR-T module (not included in the kit. DDR-T support requires DDR-T protocol soft IP)
