Feature Summary
- DDR3 SDRAM components
- Introduction of asynchronous RESET pin
- Support of system-level flight-time compensation
- On-DIMM mirror-friendly DRAM pinout
- Introduction of CWL (CAS write latency) per clock bin
- On-die I/O calibration engine
- READ and WRITE calibration
- DDR3 modules
- Fly-by command/address/control bus with on-DIMM termination
- High-precision calibration resistors
- Are not backwards compatible—DDR3 modules do not fit into DDR2 sockets; forcing them can damage the DIMM and/or the motherboard
- Technological advantages compared to DDR2
- Higher bandwidth performance, up to 2133 MT/s standardized
- Slightly improved latencies, as measured in nanoseconds
- Higher performance at low power (longer battery life in laptops)
- Enhanced low-power features

Famous quotes containing the words feature and/or summary:
“The paid wealth which hundreds in the community acquire in trade, or by the incessant expansions of our population and arts, enchants the eyes of all the rest; the luck of one is the hope of thousands, and the bribe acts like the neighborhood of a gold mine to impoverish the farm, the school, the church, the house, and the very body and feature of man.”
—Ralph Waldo Emerson (1803–1882)
“Product of a myriad various minds and contending tongues, compact of obscure and minute association, a language has its own abundant and often recondite laws, in the habitual and summary recognition of which scholarship consists.”
—Walter Pater (1839–1894)
