It is internally configured as an octal-bank DRAM. The 2Gb chip is organized as 64Mbit x 4 I/O x 8 bank and 32Mbit x 8 I/O x 8 banks . These synchronous devices achieve high speed double-data-rate transfer rates of up to 1600 Mb/sec/pin for general applications. The chip is designed to ply with all key DDR3 DRAM key features and all of the control and address inputs are synchronized with a pair of externally supplied differential clocks. Inputs are latched at the cross point of differential clocks (CK rising and  falling). All I/Os are synchronized with a single ended DQS or differential DQS pair in a source synchronous fashion. These devices operate with a single 1.5V ± 0.75V and 1.35V -0.0675V/+0.1V power supply and are available in BGA packages.
