32MB Synchronous dual in-line memory module (DIMM) DRAM for Cisco 2600XM Series Routers
The Cisco 2600XM Series of Modular Routers ship as standard with 32 MB of onboard Flash and have two slots for SDRAM.
The memory capacity of the Cisco 2600XM platforms can now be increased to 256 MB of synchronous dynamic RAM (SDRAM) using a new 128-MB SDRAM dual in-line memory module (DIMM). This new 128-MB DIMM offers higher-density memory, providing the ability to support memory increases to 256 MB of DRAM (with the correct ROMmon)
