The action of prototypes with the standard RAMs DDR4 DRAM was demonstrated during the ISSCC
In the market, the new standard memory should start coming only from 2013, but it is expected that by mid-2015 it represents 50% of the RAM market.
The new pattern is more efficient than current capacity not only throughput, but also in energy consumption. The data transfer rates of DDR3 current range from 800 MT / s (megatransferência) and 2133 MT / s, and require a voltage of 1.2 volts to 1.5 volts to operate.
Since memories DDR4 shown in ISSCC transfer data at a speed ranging from 2133 MT / 4266 MT / s, and need voltage of 1.05 volts to 1.2 volts to function. Being more economical, it is expected that the DDR4 reduce by 40% the total energy consumption of RAM in a PC.
