Types of Memory
The router has the following types of memory:
• Dynamic RAM (DRAM)—This is the main storage memory for the router.
DRAM is also called working storage and contains the dynamic configuration
information. The router stores a working copy of Cisco IOS software,
dynamic configuration information, and routing table information in DRAM.
• Nonvolatile RAM (NVRAM)—This type of memory contains the startup
configuration.
