Chapter 2 SDRAM and DRAM Memory Systems Overview
The memory systems provide the following functions:
•
Main memory (DRAM in the NPE-100, NPE-150, and NPE-200; SDRAM in the NPE-175,
NPE-225, NPE-300, NPE-400, NSE-1, NPE-G1, and NPE-G2)—Stores the running configuration
and routing tables. The Cisco IOS software executes from main memory.

and routing tables. The Cisco IOS software executes from main memory.
•
Shared memory—Used for packet buffering by the router’s network interfaces.
•
Flash memory—Stores the boot helper image software. The boot helper image allows you to boot
the router when PC cards do not contain a valid system image. It also allows you to boot the router
from a network server.

Previous documents stated that the NPE-175 was also supported on the Cisco uBR7200 series routers. Because the NPE-175
has reached its end of life and was never made orderable on the Cisco uBR7200 series routers, it is no longer shown as
supported on the Cisco uBR7200 series routers.
