Description

The H5TQ1G6(8)3DFR-xxx series are a 1,073,741,824-bit CMOS Double Data Rate III (DDR3) Synchro-

nous DRAM, ideally suited for the main memory applications which requires large memory density and

high bandwidth. Hynix 1Gb DDR3 SDRAMs offer fully synchronous operations referenced to both rising and

falling edges of the clock. While all addresses and control inputs are latched on the rising edges of the CK

(falling edges of the CK), Data, Data strobes and Write data masks inputs are sampled on both rising and

falling edges of it. The data paths are internally pipelined and 8-bit prefetched to achieve very high band-

width.
