The XDR DRAM device is a general-purpose high-performance memory device suitable for use in a broad range of applications, including computer memory, graphics, video, and any other application where high bandwidth and low latency are required.

The 512Mb XDR DRAM device is a CMOS DRAM organized as 32M words by 16bits. The use of Differential Rambus Signaling Level(DRSL) technology permits 4000/3200/2400 Mb/s transfer rates while using conventional system and board design technologies.
XDR DRAM devices are capable of sustained data transfers up to 8000 MB/s.

XDR DRAM device architecture allows the highest sustained bandwidth for multiple, interleaved randomly addressed memory transactions.

The highly-efficient protocol yields over 95% utilization while allowing fine access granuarity. The device's eight banks support up
to four interleaved transactions.
