The 4Gb Double-Data-Rate-3 (DDR3(L)) DRAM is a high-speed CMOS SDRAM containing 4,294,967,296 bits. It is internally configured as an octal-bank DRAM. The 4Gb chip is organized as 64Mbit × 8 I/O ×8 banks and 32Mbit ×16 I/O ×8 banks. These synchronous devices achieve high speed double-data-rate transfer rates of up to 2133 Mb/sec/pin for general applications. The chip is designed to comply with all key DDR3(L) 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 CK (overline) 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±0.075V or 1.35V -0.067V/+0.1V power supply and are available in BGA packages.
