     5=== On-Chip Memory ===
     6The 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 ===
     9The 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.

     11In 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).
