3.2. Memory
DRAM
The EM-X270 board is assembled with 128 Mbytes of Synchronous DRAM. The SDRAM
interface is 32-bits wide and runs with a 100 MHz clock.
NOR Flash
The EM-X270 is assembled with 1 Mbyte of linear (NOR) Flash ROM. This memory
space is used for the boot-loader and system setup data storage. The setup block contains
vital production information including boot-loader configuration, PCB revision,
manufacturing stamp and MAC addresses for Ethernet and WLAN.
NAND Flash
The EM-X270 features 512 Mbytes of NAND Flash.
The NAND Flash is a block device – optimized for block read and write operations rather
than for random access. It is used for implementation of a Flash Disk, regarded by the
operating system as a regular disk drive.
