| 5 | === On-Chip Memory === |
| 6 | The V4 FX100 FPGA provides 376 18kb RAM blocks (6.7Mb total). Logic slices can also be used as RAM (what XIlinx calls ''distributed memory''); the FX100 provides up to 659kb of distributed memory. |

| 8 | === DDR2 SO-DIMM === |
| 9 | The WARP FPGA Board v2.2 includes a DDR2 SO-DIMM slot. This connector is routed to dedicated FPGA I/O and clocking resources and supports up to 2GB modules. |
| 10 | |
| 11 | In order to use a SO-DIMM, the user FPGA design must include a DDR2 memory controller. Thankfully, Xilinx provides (and maintains) a high performance controller as part of their Multi-Port Memory Controller (MPMC). |
