Device Memory Location is basically a location where a specific memory of a device either it could be permanent or temporary for a device.

A Cisco device has four memory types. Each is used for a specific purpose:

- ROM, or read-only memory, holds the POST, bootstrap, ROMMON, and RXBoot microcode. The POST (power-on self test) is a basic inventory and test of the hardware in the device. The bootstrap is responsible for finding an operating system to load. ROMMON is a minimal command set that can be used to connect to a TFTP server and restore a missing or corrupted IOS image. RXBOOT is a mini-IOS that has a much more familiar command set than ROMMON and more features, so it is easier to use for IOS restoration from TFTP.

- Flash memory normally stores the IOS image file. Because flash is simply a file storage area, assuming that you have enough space, you could store other files here as well, perhaps another IOS version or backups of a configuration. Flash can be either SIMM cards on the motherboard or PCMCIA cards either externally accessible or inside the case of the router on the motherboard.

- NVRAM is Non-Volatile RAM; this means that it will not lose the data stored in it when the power is turned off or fails. The startup-configuration file is stored here.

- RAM is similar to RAM on a PC; this very fast memory is where all dynamically learned information is stored, such as routing tables, ARP cache, and buffers.
