The Qimonda 1-Gbit GDDR3 Graphics RAM is a high speed memory device, designed for high bandwidth intensive applications like PC graphics systems.
Features
* tWR programmable for Writes with Auto-Precharge
* Data mask for write commands
* Single ended READ strobe (RDQS) per byte. RDQS edgealigned with READ data
* Single ended WRITE strobe (WDQS) per byte. WDQS center-aligned with WRITE data
* DLL aligns RDQS and
Applications
* like PC graphics systems. The chip is programmable into two different configurations. In the default mode the architecture is organized as two 512 Mbit memories of 8 banks, each (two CS mode). In an alternate configuration, it behaves as a conventional, 8-bank 1 Gbit DRAM (one CS mode). Note that at
