Overview
The 1Gb Double-Data-Rate-3 DRAMs is double
data rate architecture to achieve high-speed
operation. It is internally configured as an eight bank
DRAM.
The 1Gb chip is organized as 8Mbit x 16 I/Os x 8
bank devices. 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 CK#
falling). All I/Os are synchronized with 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.
