64M x 16 bit DDR3 Synchronous DRAM (SDRAM)
Advance (Rev. 1.0, Jul. /2015)
Features
Overview
JEDEC Standard Compliant
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.

Power supplies: VDD & VDDQ = +1.5V ± 0.075V
Operating temperature: 0~95 C (TC)
°
Supports JEDEC clock jitter specification
Fully synchronous operation
Fast clock rate: 667/800/933MHz
Differential Clock, CK & CK#
Bidirectional differential data strobe
- DQS & DQS#
8 internal banks for concurrent operation
8n-bit prefetch architecture
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
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 differential DQS
pair in a source synchronous fashion.
