Dynamic random-access memory (DRAM) for main memory and shared memory (Cisco 261x and
Cisco 262x routers)
Synchronous dynamic random-access memory (SDRAM) for main memory and shared memory
(Cisco 26xxXM, Cisco 265x, and Cisco 2691 routers)
Nonvolatile random-access memory (NVRAM) for storing configuration information
Flash memory—Stores the operating system software image. In Cisco 2691 routers, flash memory
is a CompactFlash memory card. In all other Cisco 2600 series routers, flash memory is a single
inline memory module (SIMM).
