The DDR3 technology and its performance parameters are the increased clock frequency, which is 800 MHz and 1,066 MHz respectively, and the supply voltage, which has been reduced to 1.5 V and 1.35 V for DDR3.
The data transfer rates for DDR3 technology are between 800 MT/s and 2,133 MT/s ( mega transfers per second) depending on the clock frequency.
DDR3 DRAMs operate at a clock frequency of 533 MHz, DDR3-1066. The doubling of the data rate was achieved by an internal change in the organization of the memory cells, with the memory cells operating internally at a lower clock rate. In addition to power management to further reduce performance, DDR3 also offers lower latency. DDR3 RAMs are used in Registered DIMMs( RDIMM) and LRDIMMs, among others.
DDR3 technology is also available as LPDDR3 in Low Power DDR technology( LPDDR). It operates with a supply voltage of only 1.2 V. The successor technology to DDR3 is DDR4.
