DDR3L Termination Voltage!

While going through a reference schematic of T1042, i found that some pins of DDR3L have been terminated with a voltage (VTT). I am unable to understand why is this termination needed? Moreover, the datasheet of the SDRAM device also shows a resistor (RTT) attached to the DQS and DQS# pins. Can anybody explain the reason? Thank you!
