MB. If SIMM is with parity, total DRAM can be up to 16 MB (on−board 2 MB will be disabled).

Note: The Cisco 1605−R Series Router has 8 MB on−board. Therefore, total DRAM can be up to 24 MB on

that router. For more information, see Comparison of Cisco 1601, Cisco 1604, and Cisco 1605−R Memory

Architectures.

Note: To install or replace the DRAM, see Installing or Replacing the DRAM SIMM in Cisco 1600 Series

Routers.

PCMCIA Flash

PCMCIA Flash is the only way to permanently store and move a complete Cisco IOS software image,

backup configurations, or any other files.

PCMCIA Flash on the Cisco 1600 Series Router is implemented using one slot for Fast PC cards (up to

16MB).

The PCMCIA Flash card on the Cisco 1600 Series Router uses the Filesystem Class "B". This is the same

type used for the Cisco 1000 Series Router and Cisco 3600 Series Router. For PCMCIA format compatibility

information, see PCMCIA Filesystem Compatibility Matrix.

NVRAM is used for permanent storage of the startup configuration that is writeable. It is also used for

permanent storage of hardware revision and identification information, and also Media Access Control

(MAC) addresses for LAN interfaces. It is a battery−backed Static RAM (SRAM). The life−span of NVRAM

is specified in the maximum number of writes and a maximum time limit. NVRAM size is 8 KB.

BOOT ROM is an Erasable programmable read−only memory (EPROM) used to permanently store startup

diagnostic code (ROM Monitor), and RxBoot. Boot ROM size is 2 MB. The Cisco 1600 Series Router runs

RxBoot from Boot ROM.

For information on how to upgrade the Boot ROM, see Upgrading the Boot ROMs in Cisco 1600 Series

Routers.

Registers are small, fast memory units used to store special purpose information, such as interrupt status,

instruction currently in execution, and so on. The location of registers depends upon their use. For example,

the main processor contains the instruction register and other control registers. UART contains its own status

also contains general purpose registers for integer and floating point data used in an instruction execution.

The different types of memory can be seen in the output of the show version command:
