Samsung has assembled new 16 RDIMM GB based on 30nm manufacturing technology, but Samsung has promised that it would start manufacturing memory chips in 20nm technology starting 2013.
Registered DIMMs or RDIMMs are server grade memory units as they consume more power than normal modules because they contain extra circuitry and components required for a register. Registered DIMMs are required for applications requiring constancy and scalability. Many motherboards can support higher memory densities.
Samsung has been working on the DDR4 development since December 2012 when it first showed industry's first 30nm-class 2 GB DDR4 unit.
Samsung is the company who introduce first DDR memory in 1997.
Once the 20nm production line set up making DDR4 memories, densities can reach 32 GB per module.
DDR4 memories will double the performance of 1600 MBits/s data rate of the DDR3 memory units.
DDR4 memory will work using a modest 1.2V voltage as compare to DDR3’s standard voltage of 1.35V. It will consume up to 40 percent less energy than DDR3’s power consumption.
Samsung has already assembled 8 GB and 16 GB DDR4 units in June 2012 and sent them over to many microprocessor and controller manufacturer for testing and development.
Features of DDR4 Memories over DDR3 :
- DDR4 memories will have double performance over DDR3 memory units.
- It will consume up to 40 percent less energy (1.2V voltage) than DDR3’s power consumption (1.35V Voltage).
