Future DRAM Types
This section explores several new DRAM memory types.

RDRAM*. RDRAM is short for Rambus DRAM, a type of DRAM memory developed by Rambus, Inc. RDRAM transfers data at up to 600MB/s, which is 10 times faster than conventional DRAMs.

The new technology will enable the DRAM's highest level of performance-1.5 gigabytes per second (GB/s) of sustained bandwidth from a single device. In addition, the technology will span multiple generations of DRAM devices-from 32-megabit to 1-gigabit densities.

The following chart shows when RDRAM might be used in the different market segments. Because new technology is usually expensive and scarce, high end desktops are usually the first market segment to implement a new capability. The proliferation of the new technology into the different market segments improves as the technology becomes less expensive and more readily available.



RDRAM is already being used in place of Video Ram (VRAM) in some graphics accelerator boards, but it is not expected to be used for the main memory of PCs until 1998 or 1999.

It requires modified motherboards, but eliminates the need for memory caches. Rambus licenses its memory designs to other semiconductor companies, which manufacture the chips. In 1997, Intel announced that it would license the Rambus technology for use on its future motherboards, thus making it the likely de facto standard for memory architectures.

NDRAM. Intel and Rambus are expected to come up with a faster version of Rambus to be named NDRAM (Next generation DRAM), that will support data transfer speeds at up to 1,600MHz.

Interesting, not much pre market activity at all, tough day
with AMD, MU and SCM blow ups...

Unclewest and MileHigh,

I think this page about NDRAM might be suspect. First, the creation date of the page is March 2, 1998 and it doesn't look like it's been updated since then. Second, it talks about RDRAM transferring at 600 MBps which should be 1600MBps (unless they're talking about one of the older forms of Rambus DRAM). I think the 1600MHz it talks about near the bottom of the page might actually be the 1600MBps number for current 800Mhz DRDRAM.

I suggest we wait for some confirmation from a more current source before we pop the cork over this news.
