The 4Gb Double-Data-Rate-3 (DDR3) DRAMs is a high-speed CMOS Double Data Rate32 SDRAM Containing 4,294,967,296 bits.
It is internally configured as an octal-bank DRAM.
The 4Gb chip is organized as 64Mbit x 8 I/O x 8 banks.
These synchronous devices achieve high speed double-data-rate transfer rates of up to 1866 Mb/sec/pin for general applications.
The chip is designed to comply 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 /CK 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 power supply and are available in BGA packages.
