SDRAM SIMM Slot

The EMM-E6 motherboard provides the option of upgrading memory capacity by using Single In-line Memory Modules (SIMMs).

The EMM-E6 comes with 4 Megabytes (MB) of Shared Dynamic Random Access Memory (SDRAM) built into the module. The SDRAM temporarily stores the packets received be the module while forwarding, filtering, and error checking operations are performed.
