Memory

Cisco 3800 series routers contain the following types of memory:

•Main memory consists of ECC DDR SDRAM. It stores the running configuration and routing tables, and buffers packets at the network interfaces. Both routers ship with 256 MB of main memory. The two DIMM slots can be upgraded with 128-MB, 256-MB, or 512-MB DIMMs to a maximum of 1024 MB (1 GB).

•An external CompactFlash memory card stores the Cisco IOS software image. The routers are shipped with a 64-MB CompactFlash memory card, which can be upgraded to 128 MB or 256 MB.

•The routers boot from 4 MB of internal flash memory. This memory cannot be upgraded.
