Description
The 1Gb Double-Data-Rate-3 (DDR3) DRAMs is a high-speed CMOS Double Data Rate32 SDRAM containing 1,073,741,824 bits. It is
internally configured as an octal-bank DRAM.
The 1Gb chip is organized as 32Mbit x 4 I/O x 8, 16Mbit x 8 I/O x 8 bank or 8Mbit x 16 I/O x 8 bank device. 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 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
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 power supply and are available in BGA packages.
