The RAM3001 memory module provides additional, high-speed memory to the XEM3001 for a variety of purposes including added buffering and low-latency storage.
The SDRAM uses only one of the two 50-pin headers on the XEM3001 leaving the other 50-pin header and 20-pin header for general use. The SyncSRAM uses the opposing 50-pin header as well as the 20-pin header.
