Memory and Storage Devices 
Memory 
There is no onboard memory, but the device has a SODIMM slot for one DDR2 module, it is recommended to 
use modules with at least 667MHz (PC-4200). The RB1100 device supports modules of up to 2GB, but due to 
software limitations, RouterOS will be able to use only 1.5GB of it. 
microSD slot 
The board has one microSD card slot which supports microSD and microSDHC cards for expanding the storage 
in RouterOS
