DDR3 works with 1.5V supply,so it needs a termination voltage half of it i.e 0.75V
LDDR3 works with 1.2V supply,so it needs a termination voltage half of it i.e 0.6V

DDR3 uses 1.5V; DDR2 uses either 1.8V or 2.5V
The DDR3 has two pairs of DQS in per data lane for optimal termination values. IT is also for signal topology and the possible swapping of the DDR3's memory side pin.Ê
DDR3 memory provides a reduction in power consumption of 30% compared to DDR2_SDRAMmodules due to DDR3's 1.5 V supply voltage, compared to DDR2's 1.8 V or DDR's 2.5 V.

DDR3 runs on lower voltage, uses less power, has a frequency of 800-2000MHz (DDR2: 400-1066MHz, DDR: 200-600MHz)and the "prefetchbuffer" is 8 bits instead of DDR2's 4 bits and DDR's 2 bits. DDR3 is the only one that has the 90 nm technology.
