1.3.2 System Memory Controller
• Single-channel DDR2 memory controller
• 32-bit data bus
• Supports DDR2 800 MT/s data rates
• Supports 1 or 2 ranks
• Supports x8 or x16 DRAM chips
• One rank - two x16 or four x8 DRAM chips
• Two ranks - two x16 DRAM chips per rank, or four x8 DRAM chips per rank
• Supports up to 2 GB of extended memory
• Supports total memory size of 128 MB, 256 MB, 512 MB, 1 GB and 2 GB
• Supports 256 Mb, 512 Mb, 1 Gb and 2 Gb chip densities for the x8 DRAM
• Supports 512 Mb, 1 Gb and 2 Gb chip densities for the x16 DRAM
• Aggressive power management to reduce power consumption, including shallow
self-refresh and a new deep self-refresh support
• Proactive page closing policies to close unused pages
• Supports partial writes through data mask pins

not support SODIMM or any type of DIMMs.
1.3.3 Graphics
The Intel
®
Atom™ Processor E6xx Series provides integrated 2D/3D graphic engine
that performs pixel shading and vertex shading within a single hardware accelerator.
The processing of pixels is deferred until they are determined to be visible, which
minimizes access to memory and improves render performance.
