Memory

For information on installing DRAM, SDRAM, NVRAM, and CompactFlash memory, see:

Memory

Cisco 3700 series routers support the following types of memory:

SDRAM—Stores the running configuration and routing tables and is used for packet buffering by the network interfaces. Cisco IOS software executes from SDRAM memory.

NVRAM—Stores the system configuration file and virtual configuration register. For more information, see Appendix C, “Configuration Register.” CompactFlash memory—Stores the operating system software image. You can increase CompactFlash memory by adding Cisco 3700 CompactFlash memory cards. See the Installing and Formatting Cisco 3631 and Cisco 3700 CompactFlash Memory Cards document.

EPROM-based memory—Stores the ROM monitor, which allows you to boot an operating system software image from internal or external CompactFlash memory.
