The ATmega32u4 has 32 KB with 4 KB used for the boot loader . It also has KB of SRAM and 1 KB of EEPROM which can be read and written with the EEPROM library . The memory on the AR9331 is not embedded inside the processor. The RAM and the storage memory are externally connected. The Yún Mini has 64 MB of DDR2 RAM and 16 MB of flash memory.
